A great MoE can be a lesser SoV and vice versa. Bitcoin's has been a great SoV so far, but you would go broke quick using it for daily transactions. And this problem increases with more adoption.

Ecash is probably the only great privacy contender to Monero, but is custodial and the mints can arbitrarily create tokens out of thin air.

Lightning receiver privacy is shoddy, and sovereign UX is the reason everyone gives in to WoS. Incentivizes middlemen that centralise the network for cheaper/succesful routing also at the expense of privacy.

L2s will always sacrifice core aspects of Bitcoin. Trade offs to all of it.
