Im fairly new to Hive ecosystem so I dont have a proper opinion on this. I, for one, with less than 100 HP, welcome every bit because I feel good when I upvote someone and send more than 0,002 HP... And also because I want to have more Hives to play those great Hive titles like @dcity or @splinterlands...
But I understand your proposition. Scarcity always help to value. However, there are lots of systems designed inside Hive to keep all those inflated Hive busy, so Im not sure its a super big problem.
Community creation is harder than tokenomics, imho. And Hive community is fantastic, and maybe due to the first experiences that a newcomer has.
Just my 2 cents ofc.
