I don't know how you can avoid discrimination. By nature of credit you have to discriminate the creditworthy form those who aren't credit worthy. On the other hand, sure, we don't need to know if someone voted for Biden or voted for Trump, is for vaccines or isn't for vaccines. You're still not providing a way for a creditor to make a judgement on someone's creditworthiness. A creditor, lacking that information may have to require advances or "security" payments which is more burdensome for the poor.

Looks at the how Japan handles apartment credit. It's a different system but in my estimation its a worse answer than Credit Bureaus are.
