This. The more money we extract from the evil fiat system the better. It only strengthens Bitcoin. It raises its marketcap, everything about ti is positive. There will always be other people that can afford or it just dont care about holding to spend some of it.
As has been explained numerous times: holding and spending are not mutually exclusive.
By spending + buying back the same amount of bitcoins, you are essentially holding (thus keeping money out of the evil fiat system) and helping the Bitcoin economy grow at the same time.
