I think loan is a scam. An economy needs, only, free funding and a tax system and nothing else. Do you agree?
Banks are giving free money! Leave a 1000$ on your bank account for a year. In the end of the year you should have something like 1002.5$. So 2.5$ for free! isn't it good?
Its not free its an interest of staying your money in their bank its because they able to used your money to lend money to other banks or client and they can earn interest for your money. Bank is a form of business and no business will give a free money.
And they have lots of operational expenses so there's no way that they'll be a charitable institution by giving away 'free' money.
