You can't loan more Bitcoin collectively than exists. And you can't print more to make up for it. The lending pool runs dry, it stays dry.
You dont have to print it up. You loan me 1 BTC then i loan it again for 1 BTC. Now there is 2 BTC worth of DEBT in the system with only 1 BTC worth of money. Bankers revel in this.
It does not matter how many people lend the single Bitcoin in a chain, the total amount of debt is still just one Bitcoin. What people mean when they say "Lend Bitcoin" is creating IOU
Alice to John then to Joe, but why would Joe borrow just to return the 1 BTC in existence? He wants to buy something. He buys a car, from luis. Luis saves the BTC.....
But, this model is broken too, since this example hinges on the lenders and debtors owing the entire supply of the currency, which simply does not occur IRL.
Its nor broken. Its the failure of the gold standard. Doesn't matter the amount of BTC in existence, It can grow infinitely in DEBTS it has to pay. I could loan 1 BTC to 10 BTC of debt
Isn't untokenized Bitcoin already redeemable in goods or services only? Or are you talking about making a gift-card esque economy where spending is restricted to specific applications?
http://www.moneyasdebt.net/ - Self issued credit is explained better here. Bitcoin as a single uniform commodity money will fall into perpetual debt, just as gold did.
