This could be doomed to failure.

Switzerland is home to swiss banks who are known to provide tax shelters for the wealthy. A large part of switzerlands economy and business model depends upon them incentivizing means for the wealthy to avoid paying the taxes everyone else must pay. As such they are far from being objective or reliable in this analysis. The most likely scenario here is they will use this as a platform to discredit ideas of money and debt being separated having value as a means of benefiting society.

On the opposite end of the spectrum, does anyone know how houses were financed before fractional reserve banking was invented? How did people afford real estate or homes in an era when the gold standard was utilized or gold and silver were the most commonly used methods of payment?

I think there are many interesting points and questions involved in this topic. Unfortunately I do not think we will ever see a legitimate attempt made to answer those questions or to disseminate information which might benefit society or civilization at large. At most all we will see from this is lpropaganda and political spin designed to influence people into supporting fractional reserve banking, tax shelters for the wealthy and other things which redistribute wealth to one percenters.
