Buying at a Bitpay PoS in Japan is just scanning a QR code, instant confirmation (Wechat easy but even foreigners can use it). A P2P sale for a non-insignificant amount of money (~$1.5k): rejected by Paypal, inter-bank transfer would take days to go through. BTC was 5 minutes to wait for a confirmation. Donations through Patreon or other require you to sign-up, go through convoluted systems that sometimes require sending your identity documents, crypto is just copy an address/scan a QR code and confirm in your usual, familiar wallet.
