I've never heard of this rootstock. Is it a BIP? It's also not what Trump is talking about. They want to back stablecoins with sovereign debt to keep the party going. They don't want gold 2.0.
Yes, there are free options though, for the Global South and anyone. One example is the 100% Bitcoin-backed USD-pegged stablecoin DLLR by nostr:npub1s7uvsn0ku29gutma9tw43m5gpwuc8y3qwapzy5pnu5jtllpgcucsyvfwc4 which runs on Bitcoin's L2 Rootstock. Such projects need more attention so that they will be equally integrated in global payment services. Exodus wallet already supports DLLR and last I know also keeps it in its company treasury.

Not a bip, stay away.
Have you looked into it? If yes, I'd be curious why you think it's not a good option. I'm trying to wrap my head around this for some time. Besides of course the best option, of Bitcoin being used as global currency.
Rootstock is an L2 to Bitcoin like Liquid. I'm not saying it's a final solution. But there are projects out there that are looking for solutions to this stablecoin problem in an as close as possible permissionless and decentralized way. I think it's worth checking these projects out and then decide whether it's nonsense or not. They are trying to help Bitcoinization. Yes DLLR doesn't have this US treasury backing like Tether, it's 100% Bitcoin-backed. But it still does the same thing. Facilitating payments in a USD equivalent.
