More transactions capacity means lower fees for the users and more potential profit for the miners.
Maybe the dummy should explain why he want the miners to go broke and the users to be unable to afford onchain transactions.

Yet, those that
pretend they care about bitcoin want to keep it
crippled onchain compared to all other coins.

This should make you wonder, who actually cares about bitcoin survival and who just pretends they do.

Blockchain sizes will grow for one, causing bitcoin to become even more centralized.
And, once you start increasing block sizes, where are you going to stop? 8 mb? 16 mb? 32 mb?
There's no limit to which you can go in that case, which doesn't sound like a long term solution to me...But.. What do i know.
