Thanks !
The problem with it is that it cannot be done in a trustless way, we'd have to have someone or "something" like a fundation to manage it and it's a whole other ordeal, but that argument could be made, like the monero foundation making investments, some of the dhf could be used to be profitable instead of sitting around. I think the idea was discussed a while ago and stakeholders were against it as but feel free to reopen the discussion :)
Also re-inflation I think it's going to be fine because after hf25 you'll be able to convert hive into hbd, thus "burning" hive.
