Where are you getting the idea that the amount people have to spend to receive block rewards effects how much money comes into markets? The only reality in which that works is one where the electricity companies use the money they've got from miners to buy Dash.
That's such a hypocritical argument.
You don't dismiss market demand when it manifests at exchanges do you ? Yet ALL of that money is just going into 3rd party pockets. It's just going from one person's savings account into another's. The only benefit to the network is that if there's more demand than supply, the price rises.
The primary market is just the same except the electric companies are simply mediating the bidding. How else would you do it and make it trustless ?
Not only that, unlike in the exchange markets they're not even receiving ALL of the money that enters the market because as the blockchain price rises the electric company also has more costs, most of which go into raising the marginal price of the coin in the primary market. So once again that argument that Ryan made was 180 degrees wrongly reasoned.
