The reward increase after 5 years from now will amount to a masternode getting roughly 0.1 DASH extra and the miner getting roughly 0.1 DASH less per block. For the individual masternode owner this is about 0.3 extra DASH per month, about 3.5 extra DASH per year 5 years from now.
You've perfectly illustrated the whole fallacy of this reward ratio circus.
It's measured in Dash - which is meaningless. What is meaningful is the
value of that Dash. i.e. the purchasing power. In all your responses to my posts you've never once addressed the issue of capital gain. Sure I can cut the same piece of cake into smaller pieces and say I have more cake if I only measure the quantity in "pieces" rather than grams. But that doesn't mean you can charge more for it.
The issue is that the market can adjust the reward ratio between masternodes and miners in DOLLARS as it sees fit. Dash protocol has control over this.
Now we're seeing a price rise. What are the implications of that ? They will be to aggravate the innate heterogeneity of the Dash new supply in terms of inherent profit margin. In other words, as price rises it becomes ever harder to overcome the headwind of profit-taking from the half of the supply that is issued effectively for "free" in the absence of some other value input to the chain such as monetary velocity (which we are not getting).

This isn't some "vague theory". It's both common sense and observed fact. When market prices rise, the profit takes are driven by the holders at the biggest gain. So building a profit-taking incentive into your protocol by generating half the supply at no cost to its holder just puts an elastic restraint on the asset that snaps its price back down after a revaluation, bringing the margins back into parity over time.
