Most bitcoiners are already keeping a large percentage of savings in bitcoin only. I don't consider that living on a bitcoin standard. You should use it, spend whenever possible, you would have a savings btc wallet and a spending one. Today we mostly have to get workarounds like vouchers, that is ok, since you would have almost no fiat, but that is no different from selling some btc for fiat and then buy what you want. When I give some btc as gift one of the questions I get most is, ok, but what can i do with this? Where can I use it? And for me one can say that lives on a bitcoin standard if you not only save but can live, spend in many places, let's say Macdonalds and Uber accepted btc, now you can get almost any food, and rides using only btc.
