What would be your argument against buttcoiners?

So basically these people that are totally convinced that Bitcoin has no value, is a ponzi scheme and will go to zero.

What would be your main argument against those claims?

Playing devil’s advocate: So for example why does Bitcoin actually have real world value? It’s not like gold, because gold is actually physical and there is a limited amount of it. Sure there is a limited amount of bitcoin too but again, it only exists on the internet, basically ones and zeros. It’s also not compared like any stocks because companies make money.

The reason I’m asking is because I’m new to bitcoin and it seems interesting to me, and the buttcoiners make some fair points. Or I’m just stupid but I want to learn more.
