So you basically confirm that any fiat currency, maybe, only apart from the major ones that are universally accepted (like the US dollar) are not real ones from a view-point of someone to whom they are of no use. In this way, they are not real currencies, and the whole issue can be happily reduced to what someone thinks about a specific currency (more specifically, whether he can pay taxes with it or not, as per your reasoning). If so, how Bitcoin is different from all these other "unreal" currencies then?
Note that for a Kenyan merchant it is of no importance if someone can pay taxes somewhere with the Japanese Yen

Up to some extent, yes the Japanese Yen will always be useless for a guy in Kenya. But imagine this. If the Kenyan government start accepting Japanese Yen as payment for their people's taxes then everything about it changes. Its like a license for everybody in Kenya to start accepting it
And what does it change in respect to your original claim?
Namely, that Bitcoin is not a currency since it is not accepted as a legal tender anywhere if other currencies are not accepted either (apart from their home countries, of course). Indeed, if the Japanese Yen is adopted by Kenyan government for payment of taxes, it will become quite useful in Kenya, but I could just as well say that the same is equally applicable to Bitcoin. In fact, the chances of some government (like that of Kenya) to accept Bitcoin seem to be a lot higher than accepting the Japanese Yen since the latter is one of many other fiat currencies out there while Bitcoin is unique (even among cryptocurrencies). Strictly speaking, the Japanese Yen is one of the major currencies along with the US dollar, British pound, Swiss franc and Euro
