I know this sucks, but idk how to feel about it. I had a large collection of physical games, much like I'd imagine most gamers do, only to one day come home and find it all stolen. Insurance pulled the rug on me, and I didn't get much for any of it. Since then I've bought everything digital and, while I know it can happen, I haven't had any taken from me since. Of course, buying all the games physically would have been way more expensive as some of them are rare collectables now. I'm just happy I get to play them. I know I could lose it all again on a whim of some CEO, but I just feel there isn't any reasonable solution.
Make sure you guys keep receipts, take pictures, secure your games, and pay extra for any collectables insurance. And don't let insurance dictate the aggregate value lost, itemize everything and get quotes. You'll still get ripped off, but hopefully you can rebuild what's important if it happens to you.
At the risk of now upsetting cryptobros (but no, I'm sure they understand all too well): we need laws. not blockchain. Even if the perfect solution was created (looks at physical), there is no incentive for publishers to use it.
And we've already seen what amazing things publishers have done with blockchain. /s
