There's no difference between "central" money and other money, though. It's all just money.

> Do we have rules that forbid specific industries from contracting loans?

Regulations differ by jurisdiction, but generally you can't do any kind of banking business without being licensed specifically as a bank. For example, if you get a car loan "from the dealership" it's not actually the dealership giving you the loan, but a bank that they partner with.

You misunderstood my question. I was asking, are there industries, say Oil or Porn, who are by law or regulation forbidden to borrow money from any bank?

I've never heard of such a thing. I would be surprised.
