this is something that could encourage more the use of bitcoin instead of fiat, i hope they will make a visa version too or for other circuits for that matter
Not really, all you doing is intertwining the two. Bitcoin was originally designed as a currency - it should be able to buy goods and services on its own without the need for conversion to fiat. The problem is that no merchants actually want to accept Bitcoin by itself - even they convert it to fiat. This presents a problem, Bitcoin isn't really a currency anymore, it's more of a commodity to be traded rather than used.
i agree with you, but that is the final step of bitcoin, before using bitcoin directly we need something like the proposal of this news, to convey people to the world of bitcoin; when many of them feel more comfortable with it, you can start to build services which allow bitcoin's payments only
then those who receive those payments need to find a way to not dump their earning in fiat, but re-using it in exchange to bitcoin again, for example for paying taxes
so the problem is the final step of money, those money(bitcoin) that are in the hands of big companies
