I think it's personal preference really. For me, I choose to use Monero whenever and wherever possible. The one thing I would refuse to use Monero for would be to pay taxes with, even if it was supported, because give unto Caesar what is Caesar's. I would not want to give those dirty fuckers my beautiful Monero. But if I'm buying my phone service, or my food, or my laundry soap, or some lotion, or whatever, I'm perfectly happy to spend Monero whenever and wherever possible. Monero means money and you both hold money for savings, and you spend money for goods and services you need in your daily life. And I use Monero for both of those things.
