I think you are saying the MN network is already oversubscribed and thus can afford to give up some nodes and shift some of their rewards to HPMNs to cover costs. I disagree. Hosting costs are in dollars and we wouldn't be discussing this if dash was $1500, then we'd all just go bare metal.
So, the question is, how sustainable and how scalable is this? More so while Sam is arguing that low fees - less income - is essential to be competitive against a product without compare. My fear is, like all tax systems, DCG will justify more rewards / votes to keep us "secure".
How to launch Platform securely is the crux of Sam's argument and his only explanation for scaling is sharding, which IIRC he said could take a couple of years, plus other more important things to do in the meantime. At the end of those two years, what incentive would there be to reverse the elitist HPMNs? - none that I see. They have built a product and roadmap to make work for works sake and there are plenty more opportunities to keep this scam going, sucking the life out of basic pleb MNs.
Sorry, I realize I went off-topic but it does all come back to the price of dash.
