But the OP is not proposing an absence of a block size limit. This is a straw man argument, and the fact that it's the second time you've made it, means you're being disingenuous.
But there IS a block size limit. It's only going to be bigger, but not infinite.
Increasing the limit to avoid raising fees is in effect asking for no limit, as the reason for the limit is to ensure sufficient fees are paid.
