choddo: If I were to ride off road and need really low pressure were a chafed or pinched flat tube would be a problem, I might consider the expense and extra hassle of tubeless necessary. I prefer my Psycho Rims and my Pick-Up tires that aren't tubeless ready.

It makes sense- anything that punctures the tire has an additional thickness of the second inner tube to work through before it releases the pressure. There are also “puncture resistant” inner tubes that are simply thicker rubber.
As above, there are “tire liners” that are tough polyurethane strips that fit between the inner tube and tire. I’ve had some success with the “Mr. Tuffy” brand liners. They can be a little tricky to mount- I inflated the bare inner tube enough to hold it in place before mounting one bead of the tire, then carefully deflating it while prying the other bead on the rim.
The Mr. Tuffies were good enough to keep riding even with large glass cuts in the tire- just a slight bump as the exposed Tuffy hit the ground.
I have not yet tried tubeless. Maybe next year.

TL are more expensive though, for sure, by about 20%

Maybe Tannus inserts (for tubes) would help ? https://theradavist.com/tannus-armour-inserts-review/

I've never tried it.
(I used Tannus insert only for tubeless setup)

choddo: 20% of what do you mean. I would need different tires, spokes and rims in addition to the special rim tape, valves and sealant. Tubeless wont clog holes from glass or steel wires from tractor trailer retreads. If it did, I would just use slime which is allot cheaper

Yeah rims and valves. All the wheels I’ve bought for the last 4-5 years have been TL so didn’t really consider that.
it will clog just about anything reasonable and when it doesn’t a plug can fill the hole in 99% of cases.
All I know is I have tried both, and there’s no contest and I spend more time trying to explain this to people online than I do standing at the side of the road.

choddo: I have followed the tubeless posts on bicycle forums with some internist. The dirt cheap sealant as you put it adds a new set of problems to a simple machine. Clogged up valves and sometimes none functional bicycle pumps due to sealant getting in them. Dried up sealant, so it no longer plugs the holes. What happens when you get a hole that the sealant or even a plug can't clog. if you carried a tube and a tire boot in case of an emergency, could you clean out items that might cause a tube puncture when you are far enough from help it becomes a problem.
I have robust tires and carry a spare tube, tire boot and a patch kit. If I were to have a flat I no it is always going to be repairable. If someone would invent tubeless for bicycles that didn't need sealant. I might consider it. For now I will stick with the devil I know. I have for over four decades.

I've been using sealant for the last three years on my road/gravel bike, my wife's ebike, her road bike, and much longer on my mountain bike.
I am not sure I have had any punctures on any of these, but probability suggests there have probably been a few that nobody noticed. We use Orange Seal endurance and top it off about every 4 months. Sometimes I have had to pick a little bit of sealant out of a valve when I am topping it off.
Overall, it is FAR less work*. Otherwise, I would not bother.
* Full disclosure: setting them up can be a PITA.

I once bought an old house, and then discovered that it had been heavily damaged in a tornado in 1930. "Great!", I said, "this house is pre-disastered! What are the odds of it getting hit by TWO tornadoes?"

Sealant levels do have to be checked and occasionally 'topped up." That is well-known.
That's a perfectly valid decision, but it doesn't mean that you should confuse your ignorance with facts. The so-called 'problems' you've identified with tubeless are imaginary.

I did fact check the info and the problems that can happen with tubeless are well known. You are acting ignorant because you have not had problems yet. The facts are that People with tubeless are finding that they need additional tools and equipment to be prepared for the problems that tubeless creates.
All my bikes are old enough to have come stock with wheels with tubes, and those wheels are still in good condition, so I'll stick with tubed tires. I recognize the advantages of tubeless, but I'm both lazy and frugal enough to choose to put up with fixing the occasional flat out on the road versus going to the trouble and expense of switching.
And, of course, the increased use of wider tires at lower pressure (the bike I ride most often has 38-mm-wide tires, which I maintain at around 50 psi) has reduced the incidence of flatting for me and many others, regardless of whether the tires are tubed or tubeless.

I've also found machine screws and wires (from auto tires) embedded deeply into my tires, with no air loss. One screw was so deeply embedded that it damaged my rim tape, which had to be replaced -- again, no air loss.
I've ridden for decades and many tens of thousands of miles on tubed tires, and also 40,000 miles on tubeless. Before you call me "ignorant" on this topic, tell us how many miles you've ridden on tubeless tires(?) The answer is obviously zero.
