Has anyone written about the legal aspects of chaumian mints? (cashu and fedimint) Particularly for Americans.

I know fedimint was designed to be regulatory friendly, but I recall the consequence was the "fedi" part gets kneecapped. If I wanted to run a fedimint for my family that would be ok but it's totally useless since within my family we tend not to exchange money anyway, it's the money in and out of the family that matters.
