I've seen games that make it work.
There's an old MMO called Neocron that had perma-degradation. Your weapon would start off at 120/120, then through use go down to like 53/120 or something when you would start to think about repairing it. But then through the repair skill you'd take it back up to 118/118 or something, so the max durability goes down each time you repair it. What made it work was that everything was craftable and scavanged, and the whole economy was set up around nothing lasting forever. If it was just a case of you getting all the best gear then leaving it at that, the whole game wouldn't quite have worked the same. It also added somewhat of a death penalty, as whenever you died your implants would fall out and take a bit of damage; same deal, they can be repaired, but eventually they're going to break. And of course, someone with a high repair skill (who could repair your gear without it taking as much perma-damage) had their own little niche market.
Think of it more like the tools in Minecraft; that Diamond Pickaxe might be pretty expensive, enough that you cherish it and use it sparingly, but when it does break it's not exactly the end of the world because you'll be able to make another one.
