I mean most are on the Ethereum main net. USDC and USDT. USDC is western regulated and USDT is eastern regulated but both are on Ethereum main net.

So lets say trump decides to ban just usdt, how is he going to do it when its on the Ethereum blockchain unless he bans ethereum too but if he does that then that will affect usdc too right?

So all 3 are like properly integrated with each other meaning they cannot be separated right?

Honestly I believe if it wasn't for stable coins Eth would be useless by now worth $0. Otherwise what people will use Ethereum for, just NFTs and selling NFTs for bitcoin not for stable coin payments? Smart contracts with what if there are no stable coins at the other end of the contract?

Eth is not a store of value like btc. Because stable coins are on Ethereum is it fair to say that the true marketcap of ethereum is ethereum marketcap plus all stable coins market caps too?

Otherwise when will bitcoin gets its own stable coin on its own layer 2 to compete with ethereum? Layer 2's none of that sidechains nonsense that leverage no security from layer 1's.
