Yeah Bitcoin is a store of value like Gold. Do you can use gold for daily payments? No.
Do you can shares for shopping? Threra a lot of good coins for small payment and daily use.
I like your comparison over there, Bitcoins is very profitable today since market is volatile and it was a huge advantage for those restaurants and even online store to use cryptocurrency as a payment method to pay bills, in this case, the products and goods will be a lot cheaper.
