The earliest discussions of Pocket Economics which I recall focused on how to insure that the dollar cost of running a node was sufficiently covered by the dollar value of the reward in POKT token. cost to developers of acquiring the necessary stake to supply them with relay usage, did not drastically increase or decrease along with drastic changes in the market price of the POKT token.
The direction chosen at that time was to use the federated nodes as price oracles and adjust reward levels the relay per stake ratio accordingly.
Edit: original post was based on some major memory errors in my brain and has been largely deleted. The edited part above is (I think) correct.
PS: Thanks for the clarifications, sorry for the early onset Alshimer’s
