It is not clear how uniformity/fungibility is any different from Bitcoin.
Most likely if an entity (company, government, individual, ect) decided to censor bitcoin transactions based on tx history, then that entity would not accept a currency like
XMR at all because tx history cannot be completely known. In this sense, XMR could be
LESS FUNGIBLE than bitcoin, or at least less accepted as fungibility may be the wrong term to use in that case.
In that case you still can't differentiate units, which is the premise of fungibility. It would simply be outlawed.
