Good luck with your 1000 1-SPR Masternodes costing you $5000/month and earning you nothing because everyone else is going to be bidding the requirement up to the max. 
But... Yes exactly! lol
Price Discovery will kick in immediately and drive the price of a DM (Decentralized Masternode) to whatever value makes sense for ALL the market participants.
The people will decide what the price should be.
Also, you can't bid the requirement up to the max, since THERE IS NO MAX!
Also, if the price of a DM gets too high, say it gets to 100k SPR, then you could only create 200 DMs with the whole coin supply, so this doesn't even make sense.
All this tells me that we will have a price discovery that will lead to a perfectly balanced price per DM.
Should the price get too high, then those DMs will all take so many SPR out of the coin supply, that the remaining allowed DMs can be setup cheaper!
So, why should a DM owner put too much SPR into his DM? He will not want to put to many SPR in a DM because this will reduce his profitability.
Because, remember, a DM with 100 SPR earns the same amount like a DM with 100k SPR. But the first one has a lifespan of probably 10 seconds.
