Yes, it's our decision, no one is forcing us to do it, if we feel uncomfortable, we shouldn't do it. But if OP is talking about emergencies and spending bitcoins as a last resort, it's not a big deal because bitcoin has also helped us with problems in life. I also don't like spending bitcoins on daily activities, but in case of an emergency and the middle of a choice, I wouldn't hesitate to use my bitcoins. There are more important things than bitcoin in this life.
In an emergency or not, bitcoin is an alternative that anyone can use as a means of payment. An agreement is needed between the recipient and the sender regarding the means of payment, if both agree then the transaction is safe without any problems.
I also wouldn't spend bitcoin as a means of payment for anything, it's against the rules of my country. But that doesn't mean I don't support bitcoin as a currency, and it's possible that I'll spend bitcoins to pay if the seller accepts them as a means of payment in a pinch. The main problem right now is, bitcoin adoption cannot be done here because of the government's ban.
