Because the problem isn’t with the currency itself, it’s with the intermediaries necessary for large scale mercantile interactions like selling games on an independent storefront.

Just because you use crypto doesn’t mean someone who holds that crypto in trust for you can’t just not give it to you if they don’t feel like it. And as there is less regulation covering that currency, you have less recourse in getting it back from them.

I can’t speak to all the positives and negatives of crypto, but I can say it is not in any way a cure-all that you can just inject into capitalism to fix everything.
