All very true, it is more stressful than I would like, but that kind of goes with collecting. You've described what collecting is, which isn't the same as gaming, but lots of us do both. I don't obsess over all things, like I don't care about the dvd or bluray movies I buy, because I'm not collecting them. I'm also not paying as much for them, which is a factor in it. If it's something I really want to play and not just collect and I have it sealed or in as mint condition as I can afford, I'll get it digitally or pick up a second copy to play and that condition won't matter. It doesn't make sense to everyone, but what does? Stressful yeah, but it can also be pretty satisfying.
I appreciate your insight, and sometimes I wish I could approach it differently, but I'm getting a little to old to change
