keep the value stable or keep the value high? two very different things; For example I'd argue Bitcoin's high L1 transaction fees keep the value unstable, but higher.
It is not obvious to me that an agent with higher investment should be allowed to notarize the payments. The system should generally work for the benefit of the users, not the HODLers, developers, miners, stakers or any other special interest group.
P.S. I think PoS is a major downgrade in decentralization. At that point, you might as well just use classical consensus: it's more secure as your relationships with notaries are explicitly established as opposed to choosing whoever happens to have the most coins.
