No, the genius idea is its major issue, just by paying you gain access to private data (people's preferences) without any kind of chain of trust to make sure that someone is actually part of the group ("market" in your terms) for which they want access to.

By paying you could know that someone around you is looking for cocaine, or is willing to sell sexual services, or is looking to match other people from the same gender, or holds a certain political view against an authoritarian government, etc.

I answered this in a sibling comment. You could acquire credibility in a particular preference from the network over time.

Sounds great, I'm going to make a "credibility as a service" startup and we'll find ways to farm whatever score in whatever fields you want.

And you can be sure government agencies will do the same.

Odd that you think this would happen for my little idea when this hasn't happened for credit cards which is possibly the largest financial incentive possible. To my knowledge, I can't buy a credit score

Finance is a heavily regulated industry, so people trust credit providers with things like social insurance numbers, which are not transferrable between people

Your service would probably not be able to tie so uniquely to an individual, so there would be ways for people to transfer it.

Or just hire a company to pretend to be you for a while.
