>> You're suggesting a subsidy for gamers which everyone else would to pay for

>No, that's not how it works. Not even close.

As far as I can tell, legislation which enables you to play a game in perpetuity instead of for a limited time will likely reduce the amount of tax revenue your gaming-related activities generate.

A useful metric to focus on here is the cost per hour of entertainment. The price of the game itself might stay the same, but the cost of your gaming itself would be subsidized.
