It’s can’t in the sense of “I can’t eat another bite.” Yes, until your stomach bursts and you die, you can eat another bite, but everyone understands what you mean.

I can’t watch YouTube with ads. The “without forcing myself” is implied.

Have you tried paying for YouTube premium? Or is there some 3rd definition of can’t you wanna make up?
Have you tried burping and jumping up and down?
Have you tried playing in quicksand or traffic?
