Personally speaking, intentionally not using or collecting credit in this world is dumb. It’s shooting yourself in the foot for basically everything longterm wise. This can be from rental agreements to buying a house to buying a car. Anything that needs to show trustworthiness. It’s stupid, but it’s how this world operates.

I would highly recommend reconsidering your mentality that you’ve given up on credit.

Also regarding the fraud. Hopefully you are currently mid battle on that because it’s not fair for you to have bad credit due to identity fraud and generally when proven that someone stole your identity they reverse all charges(for you) and reverse the credit score that went with it., After all, you never actually spent the money. But that’s a long and lengthy battle
