Yep, I would use it without hesitation. I mean, I buy stuff with bitcoin on almost the daily basis. Not directly (peer to peer) but via Binance Visa card, so of course I would rather avoid sending my bitcoin centralized exchanges and avoid all the risks of using them, and instead just do it directly, as intended by Satoshi.
Example: Let's say I purchased a car for 1 bitcoin today but next week the value of Bitcoin has doubled meaning I was probably better off using fiat.
I stopped thinking that way years ago, so I don't care about past and how much would I have if I didn't spend.
