And what happens in that 15 minutes? Does the user have access to the site in that time? If so, what happens when the transaction doesn't validate? Just lock out their access? Ok. You can download quite a bit in 15 minutes. And then you can just run another fraudulent transaction to regain access.

Which is great for actual fraud. Especially when you make it super easy to do. Like buying coins online and clicking a button.
You do realize the issue is that neither side of a payment fully trusts the other, right? We can't just pass the ball to whichever side when it's most convenient. Cash works because it's in person. You see me, I see you. I hand you cash, you hand me a product/perform a service.

Bitcoin is not anonymous. It's at best pseudonymous. Not to mention, if the bitcoin can reach you, you are reachable. It can be made difficult, but no matter what there has to be a path back to you in order for you to receive the coins.
And you are ignoring that crypto is incredibly volatile. I think bitcoin went from near $20,000 to $6000 in this year alone. Imagine losing 70% of your value just because. That that $5 you collected from Joe Shmoe in January became $1.50. It's why a lot of businesses started backing off of it. It's just too volatile to be used as a currency. And let's not pretend that there's any other crypto worth talking about other than bitcoin. Ethereum, Litecoin, BCH, etc all follow bitcoin.
