Sats are not fungible, if they were, it wouldn't be possible to end up blacklisted or help blacklist others by sending them tainted sats. As anyone who was mindless about this and who interacted with the wrong service can attest to.

It is no wonder the governments of the world are leveraring this weakness to attempt to enforce their draconian financial surveillance ideals.

I suspect it is also why Bitcoin was left mostly alone for as long as it was.. you can see what the real threat to their little surveillance is by what coins are getting delisted from exchanges in a coordinated, predicable, and behind-the-scenes move.

Having said all that, yeah the whole "rare eats" nonsense is... well, nonsense.
