Demurrage would seem to discourage Merchants joining on freicoin/bitcoin. With fees, you get what you charged for. With demurrage I see destroying money that people own, have earned, and have every right to spend, and give it to whoever they want. (This is an idea of bitcoin representing value owned. A very attractive idea to me.) For what? To avoid an honest Supply/Demand economy in bitmining?
The concept of people leaving the bitmining pool and joining thus creating a raise and drop in prices is really simple supply and demand economy. This is free market at it's finest and simplest.
I feel strongly about the apple scenario. Somebody answered the question 'Why buy an apple today when tomorrow you can buy two?' with 'Because your hungry.' Which is exactly the point of it! With the deflating dollar I need to buy a dozen apples today to retain my dozen apple value that I received in pay for my hard work, even though I won't be able to trade those apples for a car I may need in the future. So I have to stop purchasing so many apples and save money at a rate that exceeds the rate of inflation, when in fact if I had saved my money and only bought apples when I was hungry I could have purchased the car sooner and replaced the vehicle more often, and all parties involved would benefit. The apple seller would be getting an increasingly valuable currency for his apple, the car dealer as well for his cars.
