> I’m convinced math would be better without infinity. It doesn’t exist.

I agree finitism and ultrafinitism are worth more development. Infinity is a hack in the sense that it effectively represents a program that doesn't halt, and when you start thinking of it this way, then all sorts of classical mathematical arguments start looking a little fishy, at least when applying math to the real world. For instance, I do think this is at the heart of some confusions and difficulties in physics.
