That's a rather simplistic view.
I'd agree it would be pointless to go off into a long and boring debate about it, but in fact a long and boring debate would be the only way to cover all the stuff you're talking about.

Without access to capital, there would be no commerce. No raw materials would move, there would be no ships built, nobody could afford to grow and harvest food on any kind of scale.

You're describing a stone age society. You eat what you catch, if you don't you die, right?

In Islam it is against the law to charge interest, and any differences between your average Muslim country and your average Western country can probably be accounted for by the Industrial Revolution.

And what's an average Muslim country, or an average Western Country?

Are we talking about the difference between Saudi Arabia and Albania?

Oh, wait, let's do Switzerland Vs Yemen.
