Fair enough. I will have to think more about it and factor in some of the things you have mentioned. I have suspected for a long time that the tap will close and I have posited a long time ago that it would be through a fork that changes the inflation rate. This isn't unexpected, but I am still undecided on whether it is the best way to go. Since I have relatively high stake, it would benefit me, but since this is a social environment, the entire population needs consideration. If SMTs pan out, they will create their own inflation pools anyway, so this might be the best way to secure the Steem infra.
RE: How viable is Steem as a currency as the Steem network must constantly create tokens to reward bloggers and enable votes (causing lots of inflation)?
