It's high trust and easily ruggable though...  And it's not secured by Bitcoin network in any way.  Cool, yes. For small amounts and groups? Maybe.

For the general masses, I just don't see it? 

 just pick a mint you trust and swap to lightning/onchain when the amounts get big. we'll even have auto-swap to make it easy. 

 That's the point. 'trust'.  Who can be trusted?  The risk of rug is real
