Yes, but you don't need more than 20-30 seconds to be confident that a transaction isn't a doublespend attempt.

After that it's only about checking if the fee is high enough.

Which can take up to 72 hours, right?

No, you just check if the fee per KB is more than x. Where x is a fee that is likely enough to confirm. This is practically instant.

I'm not sure "likely enough to confirm" is going to go over all that well with many merchants, particularly when that chart shows the price-per-byte jumps all over the place rapidly.
