Becoming confused or blind because you're a bit low on oxygen can cost you
your life.

Normal, healthy people do not become confused flying at normal GA
altitudes due to lack of oxygen and you don't become blind at any altitude.

Since in most GA aircraft it is a struggle to get to an altitude
where oxygen is required and except around places like the Rockies
seldom necessary to go that high, most people don't bother with it.

There are altitudes where it is required, and altitudes where it's just a good
idea. The latter are much lower than the former. If you decide you don't
need it, you don't have to use it (unless regulations require it), but I don't
see what harm there is in having it on board.

That's because you have never payed real money to fly nor ever performed
real pre-flight planning.

Once again, no context to understand the answer.
