I've never had a valve core clog so badly that it was unusable; even if that did happen, I can buy a ten-pack of cores for about $8 on Amazon and can replace one in about 30 seconds. I've never experienced (nor heard of) sealant causing problems for bike pumps.

Sealant levels do have to be checked and occasionally 'topped up." That is well-known.

If the sealant doesn't plug the hole, most often a plug (which can be inserted in about five seconds) will do the trick...I might then have to put in a little air to get the tire up to pressure. It's still MUCH faster and easier than dealing with a punctured tube. If for some reason a plug won't work, then I just insert a tube -- just like I would if I were still using them every day.

I carry the same things even when I am riding on tubeless tires -- and I, too, know that any problem is repairable in the field. The difference is that I (and other tubeless users) don't have to fix as many punctures in the field.

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.
