But how is it wrong? Saying "there's an infinite amount of X because someone can create Y and everyone will switch to Y and call it X" is a silly pointless argument. Of course that could happen, but it would require basically everyone to agree that Y is X and to switch over to Y, which is basically an impossible task, let alone when tens or hundreds of billions of dollars are involved. It's a criticism that can be applied to literally anything.
