In a working payment system, the scenario where someone initiates a valid dispute nine months after the fact would be extremely rare: it would be limited to a few types of physical card theft where the card owner is unable to report the card missing for some relatively unusual reason. We just don’t have a working payment system, so unfortunately this stuff is incredibly common and everyone has to suffer because of it.

There are genuine cases (travel and lodging are the obvious ones) where people tend to pay for things months in advance. I don't see it going away. If you can come up with a cheap, effective, convenient payment method to cover these things, you are on a winner. I don't think it's possible because the time horizon creates risk, there is no avoiding it.
