I tend not to want to change the front der anymore than necessary (like at all).
So, I already have plans to adopt your suggestion, but in a slightly different manner. Great minds think alike
Sounds like you are a secret 1x fan :-)
For chain economics consider 3 chains cost a bit more than a regular cassette (unless you have one of the super expensive XTR 12-speed or SRAm 12 speed etc.). I change my chains when chain elongates to 0.5%.
Take steel ruler and measure 12 links. If they reach 12" and 1/16", replace. Or measure 10 links and replace at 25.5 cm. Both measurements are at about 0.5%.
You will get around 3 chains out of oen cassette and 2-3 cassettes out of one chainring. It depends a bit on if you use all cogs evenly, the 11T wears fastest. YMMV.
For chain maintenance just wipe off the chain after dirty rides or every once a while. Re-lube and wipe off again after the oil soaked in. If you get some dirt on the RD sprocketts, wipe off every once a while. unless it gets muddy, this is all it takes.
How long all gear lasts depends on your force, dirt, water etc. MTB drivetrain parts typically last shorter than road parts due to dirt.
I always buy the cheapest parts, I don't think expensive chains and cassettes last that much longer. Quite the opposite when it comes to expensive light-weight parts with aluminum and titanium instead of steel. any shimano, SRAM or KMC chain will be good. any shimano, SRAM or Sunrace cassette will be good for the price.
