The design of HBD makes it loosely pegged to something. Despite the name having "dollars" in it, we can change the peg from USD to something else and potentially rebrand HBD.
If the argument is that stablecoins themselves, regardless of the peg don't belong in the crypto space, this holds some truth to it. But as long as we spend money in fiat prices instead of crypto, stablecoins are needed as a sort of bridge between the two worlds.
