You have 5 mining businesses, A, B, C, D and E, each of which invest around $200k in mining equipment. A is a pure mining operation, B to D 4 are hybrid mining operations. Assume the hybrid operations acquire their masternodes at the time of purchase of the mining equipment and dispose of them at the end so there's no net investment in Dash.

Note that, despite all making exactly the same investment in mining and contributing exactly the same hashrate to the difficulty level, B to D reach mining profitability far faster than a pure miner because they're operating under ever reducing effective difficulty levels and so are more profitable.

The shortfall in difficulty for operations B-D is what's quantifiably lost to the network in terms of supply scarcity compared with 100% mined coins. This type of gaming isn't possible and everyone has to mine at 100% difficulty.
