How do other uses compromise Bitcoin?

All uses have to compete economically for block space. If non monetary uses beat monetary uses, then Bitcoin as money fails.

That would say more about what people think of financial sovereignty than it does about art or degen trading.

As I see it, the way things are going right now, the threat to Bitcoin as money doesn't come from spammers, it comes from Number Go Up narrative pushers who tell people that ETFs and trusted third parties are fine to use because you'll get rich regardless.

That line of thinking is what causes demand for block space to drop, thus making it so cheap that people play stupid games with block space.
