The first question is. Why is inflation needed in our current system?It's an indirect tax and it's a tool supposed to speed up the money flow. The faster the money circulates, the more value will be created.
The second question is. Is bitcoins' value guaranteed?No, bitcoin has to compete and can lose "value" in the process.
Third question. How will states finance themselves in a future world?Look at some implementations of regional currencies. (e.g.
http://community-currency.info/en/currencies/brixton-pound/)
Two implementations (a combination is possible):
- Demurrage (e.g. if holding a coin for more than 3 month the customer as well as the business owner loses 0.25% every month)
- Transaction (sales) tax (e.g. if a business owner is paid with local currency (e.g. Brixton Pound) he has to pay 2.5% if he wants to receive bitcoins instead.
The last sub-question is. Why would a business owner use this?Because after all, we are all social beeings living in a neigbourhood. Profit maximizing only works, where people don't know each other very well. If I can see my money working for the greater good, I have nothing against opt-in taxes.
Both implementations are easily enforceable/auditeable due to their digital nature. It already works in small communities
despite beeing based on inflationary fiat currencies.
The "generated" money will go to one or many causes, the customer pre-defined. (e.g. a hospital, a school, a municipal administration,...)
P.S. Sorry for capturing your thread.
I don't think inflation on the base layer of a digital currency is a good idea. If it is needed, to secure the network well that's another case - I would go with the block-reward instead. If you really want an inflationary currency build it upon layer 2.
BTW - I am also open for suggestions.
