Of course, if goods and services were priced in bitcoin then that would be part of a good argument that bitcoin is actually a currency.
Check out the Lightning network, it's much more about currency/goods/services as a Bitcoin service.
With the possible exception of dark web drugs/gun/murder-for-hire/WHY every case I've seen of BTC being used for goods and services involves dynamic currency conversion. i.e. the price is in, say, USD and the amount it costs in BTC is derived from the USD spot price of BTC.
It's like I swipe my credit card in Japan; the price is in JPY but I pay in USD.
I would be interested to see any counterexamples.
