There is no "more fungible". It is either fungible or it isn't. Provenance can either be determined, or it can't. Sure there may be a degree of difficulty to determine provenance for some things, but if you cannot determine provenance at all, there is no degree.

"Fungible: being something (such as money or a commodity) of such a nature that one part or quantity may be replaced by another equal part or quantity in paying a debt or settling an account"

That definition doesn't mention provenance, even if I concede that something can't be "more (easily) determined" or "less (easily) determined".

My point is that if 99% of debts can, in practice, be paid (or transactions made) without either party paying any attention to the provenance of the coins, then the coins are fungible.

If there were reports of a significant number of a people being unable to transact because their bitcoins were blacklisted, then I would believe that bitcoin is significantly less fungible.

Whether that lack of fungibility is more significant than Monero's differing level of merchant adoption (for which I also don't have statistics) is then another question that a user has to weigh up.

It would be very unfortunate to be in that 1%, particularly if the implications were dire economically or for liberty. 1% is an enormous percentage. I personally wouldn’t even settle for 0.1%.
