--EDIT Not sure why I get the down vote. Pretty neutral comment. I think the credit score is just a sham. If someone wants to get a loan I don't see how a single number has any bearing on reliability. It boils a multi variable question into one number. Further, the number could be quite misleading. Also I don't think any 3rd party should have this data without a written contract from the individual. Maybe that will get more down-votes, but I at least can see some disagreement in that. However, "I would enjoy not having a credit score" is just a statement...
I view loans negatively. If I can't save up for it. I don't need it. I am certainly not going to pay more for something thanks to that pesky interest. I also got rid of all my credit cards 5 years ago, and made certain to never take out any more debt. Not even for a house.
The only exception I could see is if I started a business as it allows for additional cash when needed. For example more orders than anticipated, and I don't get paid till the customer has the product. Either, customers suffer delays or infuse some extra cash to increase cash flow, but then immediately pay it back.
