Cool, this way you could have a private store for each user. I wonder if you could also use this for roles and federated signups somehow. Also maybe you can enable primitive sharing if you use wildcards on both sides.

Could you elaborate on the setup you used? I am in a similar boat and thinking about doing this.

I am not sure. If I understood correctly then you separate between price gauging and currency devaluation. But even in the most perfect currency devaluation, where every one in the supply chain would increase their price by exactly the rate of inflation. What would happen to everyones profits? They would also go up.

Price gouging is rising the price of a product above market price.

But what is the market price? If people are willing to pay for it then its the market price. So its adjusting the price to the current demand. There are times where this is unethical for example profiting from wars and disasters, but generally this is how things go.
