if you stay in one place for a while you don't need no stinking navigation, and when you are visiting places, you only need it when you need to venture into the unknown, once you know it, you don't need it.

if more places accepted lightning though, that would be a different story, i'd bring my phone and leave my bank card at home, in fact i'd cancel the bank account if my local supermarket and bar both accepted lightning, because that's the only two places i spend my money often, the convenience of being able to only sell my bitcoin immediately to a payment card is why i still stick with it, i keep my sats as sats, and only spend at the last mile.
