This question is about a decade too late. Don't worry, though, it's going to happen on consoles, too.
It happens on consoles all the time. The Wii U games are pretty worthless if you upgrade to the Switch, unless you want to a bunch of different consoles around just to play a couple older titles. Nintendo is the master of repackaging their core titles for a new system and making the audience pay full price for it, and they almost never go down in price.
On the PC, if I need to re-buy an older title, I can usually get it pretty cheap at least.
But really, I'm not all that worried about losing access to a game I bought in the past. I barely have time to play the new games. If a game is important enough for me to want to replay it a decade later, then I usually don't mind dropping a few bucks to play a remastered version. They are just games. I have plenty of products that don't age well, and games are on that list.
