[Spaceships] Islamic Banking and Financing Spaceships Purchases

[whswhs]

No one who is lending money for commercial reasons, rather than within a family, to a friend, or as an act of charity, would accept getting the same money back a year later. "I'll pay you now" is not equivalent to "I'll pay you a year from now" in value—nor to "I'll pay you now, but you have to agree not to spend the money till a year from now." The latter gives you fewer options, and the ones you don't get include the most urgent ones.

So if you do prohibit lending X amount of money and getting back X+x, one of three things will happen: Either you get workarounds, or you have desperate borrowers going to black market lenders (who will charge higher interest rates and/or use brutal enforcement methods), or you simply have no ability to borrow money, no matter how desperate your need. In GURPS terms, the first two rely primarily on Law and Streetwise, respectively. (Whereas if interest is legal, you just need to make a Finance roll.)

One of the common workarounds, though, is the understanding that you are lending money to a productive enterprise—in effect, sharecropping. Your funds pay for assets that increase the output, and thus you're entitled to share in the output you've helped produce. That doesn't do anything for consumer loans, including purchase of consumer durables such as cars, houses, or yachts, but it would seem to apply, at least potentially, to spaceships.
