Most peoples' answer to this depends on how long they've been in crypto.

If I was a brand new arrival absolutely not. Why would you? There are options that are non volatile and less hassle. Obtaining your crypto would've been a grind.

If you're sitting on a pile of free gains then why not? Time to realise them by buying some junk.

The latter are in a minority so I don't think any such place would thrive. And most of the time the existing places like this charge you more money for the honour of paying with crypto with much worse choice. I'd never take a shittier deal because of some sentimental attachment to my payment method and anyone who does is a numpty.
