I’ve never ‘needed’ a credit score unless I was requesting a line of credit. I’m which case a credit score is better than the alternative where I need to personally know someone that the lender already trusts and trusts their ability to trust other people.
You don’t ‘need’ a credit score but if you want a line of credit then it’s good to have. Otherwise you get the products that they offer to high risk individuals which costs a pretty penny.
