Your point was that a fix-money-supply system is logically provable to be inherently unstable. Have we moved the goal post?
I don't quite understand what you mean. Anyway, you should keep in mind that if you want to logically disprove something you should yourself use logic but not refer to examples. Regarding your examples themselves, the Italian Renaissance cities are irrelevant as such since their economies are not sustainable on their own at all, in the first place. They were basically bankers and traders (read resellers). Without the rest of the world, they would quickly die out in a matter of months if not weeks. And which book are you talking about?
The producer-consumer example was my invention, just in case
Sorry, you're the one who has to prove that a fixed-money-supply economy is inherently unstable, since that was your assertion. I only have to provide counter-examples
This certainly won't do
I think that I have logically proven my point. Ultimately, this is irrelevant (since you still consider my arguments as not sufficient). What is relevant here is that you can't just pop up and claim that my point is shaky or invalid. Basically, you should either disprove it by showing that it is internally wrong and inconsistent using the same logic as I used (which you simply can't since it is logically perfect) or somehow prove that this model, though internally consistent and coherent, is not applicable to real life. Obviously, your so-called example are not disproving (or proving, for the record) anything in any conceivable way
Trade was only one of many supporting factors for the Renaissance economy. Every economy has them. I suppose you're going to say that if a Medieval crop economy was subject to destruction by climate change, it would prove that fixed-supply-money is inherently unstable?
Or that the economy was no example of a stable, fixed-money-supply system?
It doesn't matter if it was only one of the factors in the Renaissance economy. What actually matters here is that it was not in the least sustainable on its own and greatly depended on the outside world. That pretty much renders your example useless. It is like claiming that you live on your own while in fact you live in the basement of your parents' house
You still have not addressed the core issue with your model, that having only actors who must increase their savings will naturally not work with a fixed money supply, so that the model was unrealistic and actually could be argued to have been chosen for its conclusions
I assume that all other actors ain't relevant. If you disagree, explain how they should be
See my original statement. I guess I'll just have to keep waiting
Honestly, I can't fathom what you mean by me "having only actors who must increase their savings". Just in case, it is about consumers and producers. Essentially, it is not about saving, it is about having enough means for pure subsistence
I laid out as plainly as possible why your model is unrealistic. Yet you "honestly can't fathom." I hope this model is not the sole basis of your "proof," but I can't seem to recall there's anything else.
Unless we have anything new to add, wouldn't you agree this discussion has come to the end of its useful life?
