And actually, I think I see your point that IF this were the only mechanism in play regarding how much people pay in fees, it could pose a problem. My counter is that it is NOT the only mechanism in play.
ETA: R2D221, hope this clarifies it for you too.
What else would make people pay a fee? I do not think alturism would pay for an infrastructure of 300 mio USD and increasing.
It's not a binary option. Raising the limit at a moderate pace, so that fees don't have to increase a substantial amount with increasing adoption, is a middle ground solution, that will lead to average fees remaining affordable but not-zero.
There are quite a few constants in Bitcoin that one could argue with, that is what we do. It is however important to do it for the right reason.
Avoid paying fees is not a right reason.
