Games

Sure, I can also do just fine without the video game market. In fact I could also do okay without the farming market as well, I would just have to put significantly more time and effort into growing my own food. The key point you seem to be missing is that we can all do without those things, we just don't want to.

You could also live without the farming market, but it would mean you might have to move to somewhere where you could have arable land, learn how to farm and how to store the produce. But that clearly would be a significant reorganization of your life, and most importantly one you don't want to make. Obviously if you had to you'd do it. Or are you so hyperbolic you'd claim you'd rather die than learn farming? Saying you need the farming market comes from a position of privilege. You're privileged enough to have the option to not have to farm so you prefer not to farm.

Replacing games with some other entertainment is much the same. The change isn't as drastic, but the reason to not want to change is the same. Being able to play games or engage with other forms of entertainment comes from a position of privilege. We're privileged enough to have an option to play games and we prefer to play games over other forms of entertainment. We don't want to lose that privilege (much like you don't want to lose the privilege of not having to farm) so we care what happens to the industry.

The only "delulu" here is you, who somehow acts like they're holier than thou when in reality you just have no respect for the very hobby you partake in.
