Commercial loans are not an issue, interest on money lent is not an issue, the credit system and fractional reserve and socialised losses for wall street are the issue. That, and the fed, but still... I'll lay it out for the slow of thinking below.

1. You want to rent a car for a week.

2. You pay 500USD to rent a car for a week.

3. The car was worth X

4. You rented X dollars for a week for 500USD.

5. You want to borrow 20,000 USD for a week.

6. You pay to rent the money for a week.

7. The money was worth X

8. You rented a car's worth of asset for a week for 500 USD.

If anyone is against interest for the mere sake of it being interest, they're against the concept of renting anything at all, whether that be a suit, car, yacht, or wedding ground.

Commercial loans are not an issue, interest on money lent is not an issue, the credit system and fractional reserve and socialised losses for wall street are the issue.
