I don't really see how moving coins to yourself is good for the economy. In fact it seems like a waste of resources, though the benefit of certainly over lost coins might be worth it.
It's not. But keeping coins moving is. Any waste of resources in this instance is negligible. But I am more likely to spend coins if I am consciously aware of them as a resource, as would be required in order to move them. The good for the economy part is emission which compensates for lost coins. They will have higher velocity than average.
Inflation is not an incentive to spend unless you are forced into using only that currency...
I am not arguing that inflation is good for the economy. I am arguing that spending is good for the economy. I am arguing that spending is more likely if you are aware of your funds.
I am not arguing in favor of punishing stale funds. I am arguing in favor of replacing lost coins. Stale coins are a proxy for lost coins.
Aside from argument, my disposition is thus: I do not favor inflation. I favor deflation. I also favor securing the network, and indeed consider it a priority above most other considerations.
Because of these dispositions, I think constant emission is a good trade-off, but do not think that exponential emission is a good trade-off.
