1- What is wrong with interest-based loans (from the point of view of macro-economics and finance) is that the money created by the multiplier effect of interest-based loans is unsustainable on the long run, and eventually leads to recession and depression
There are always ups and downs, yes, but the long-term trend is up, as you can see from any graph of the stock markets over the last 100 years:
The Big Picture | 100 Year Dow Jones Industrials Chart
And measures can be taken to buffer the downs so they are not catastrophic. After the Great Depression of the thirties, such measures were put in place. Since then there has been an increase in the standard of living, new technologies, and better infrastructure despite the downs. I mean we have had several recessions in the last thirty years, but at no time did we revert back to how things were, say, 100 years ago.
I'm starting to wonder if Islamic economics had something to do with the stagnation of what was once the world's largest empire, the Ottoman empire, and its finding itself hundreds of years behind its European competitors at the turn of the century.
Are interest-based loans allowed in Saudi Arabia, Iran, Egypt, Indonesia, and so on?

2- When buying property, most people can't afford to pay 100% up front. There is always demand for buying property on instalment
There is always buyer demand to buy on installment, okay, but there is also always seller demand to sell 100% up-front. There will always be situations, whether a seller is selling an apartment or a car or a chicken sandwich, where it is far better for the seller to only sell to those who pay 100% up front. You have not addressed those situations.

3- Yes, on the short run it looks ok, but the problem arises when the negative aspects of interest and "ficitious" money created by the multiplier effect of commercial banks on the long-run leads to whole system to collapse
I would agree with you if you were talking about totally *unregulated* lending. There has to be oversight and regulation so that people don't go wild. But there also has to be lending for there to be significant growth and innovation. The "whole system" has never collapsed in dozens of cases for over 100 years, as far as I know. Look at the US, France, UK, Australia, Germany, Japan, and on and on.....their economic systems are still here. They had downturns, yes, but the long-term trend has been up. They're still producing the best cars, the fastest computer chips, and cures and treatments for diseases that used to be fatal. Some risk and some occasional loss is the price you pay for growth, innovation, new technologies and more creativity. Compare that with the Middle East, where (and correct me if I'm wrong) the most thriving areas are places like Dubai, which required a lot of initial capital to get it started.

The long-term negative harm caused outweighs the short-term "advantages", and that one of the main problems of the business world of today: it's too short-term oriented and doesn't care much what will happen later on ... But when it happens (like in the 1930's) it's a major disaster which affects all people as it harms the whole of society ...
What is "short term" about the creation of the personal computer? Or Henry Ford's assembly line production and creation of an affordable car for the common person? Those things are still with us today. They aren't going to go away even during temporary recessions. Obviously far more people owned a car during the last American recession than owned one in 1900. And we wouldn't have things like that if banks didn't lend money to entrepreneurs, inventors, and researchers.
