What I am advocating is a change that fixes what appears to be flawed while there is time. You cannot hide from the economic reality and simply focus on the technology. A digital currency must fulfill the needs of the users if it should expand. I want to believe, the community wants Bitcoin to grow and be accepted in many places. If it is just a fun project to test out a technology, then maybe I am in the wrong place.
I hope you realize that there is room for several approaches. In order to implement your stuff, there is no need to alter bitcoin in any way. Just fork it, and use it with people who share your point of view about money. The bitcoin community will keep using bitcoin, and your community will use your inflacoin.
Bitcoin doesn't even need to be accepted in many places. If I want to buy something in a "inflacoin-only" store, I'll just buy enough inflacoins with my bitcoins on the exchange market. And everyone is happy.
