> How does blockchain help with this? The problem isn't that there isn't a record of your purchase on a ledger somewhere, the problem is that the software environment in which your purchase is meaningful is no longer running.

The reason that environment no longer runs is because the company decides it's no longer profitable to run it. Blockchains build incentives to run that environment into the operation, so as long as there are users willing to pay, and the environment is efficient enough, in theory the environment should never not be running.

This gets stronger if you share that environment with multiple games.
