How can you centralize 3000 MN's?
Because a comparatively few people will end up running all of them. You'll have a situation as bad as a handful of people controlling other PoW coins' hashrate via their centralised pools.
You are right about my calculations but solidify's my argument. With 5 million spr you can only fund 3000 MN's with 1666 SPR, making your monopoly even weaker than i thought.
I still have no idea what your point is here, sorry.

And Mr Spread was talking about a hard limit on the max number anyway.
If the coin become's centralized it will lose value and become less profitable for the "monopoly" rendering it financially nonviable.
Uh huh, miners who mine via pools render the whole value proposition of a 'decentralised' cryptocurrency worthless, but it doesn't stop them doing it.
