That's way too big of a generalization. The fact is that technology advances and makes other technology obsolete, and the pirates are dwindling while DRM companies are getting more and more money to fix the issue. It is not going to just magically reverse at one point. If anything the people are just going to get more accustomed to it like they have already with copyright laws, subscription services and simply not owning anything digital anymore.
The second thing you're not addressing is how long the "ebb and flow" takes anyway, if gaming piracy has a resurgence in 50 years then I don't think I'm gonna care much about it by then lol. Blizzard games aren't getting cracked anymore and by the time they do, if ever, I'm not going to care about them.
