Except the crux of Sam's argument is that the free market will balance itself out. In any event, a switch to Platform can be staged via Sporks.
The 250/1000 dash solution has a few important advantages:
1. Instead of making the network more elitist, this would make owning a basic masternode more accessible. A real boost to marketing.
2. Once someone has a 250 dash masternode, the upgrade to a HPMN is 750 dash.. which is more achievable than the 3000 dash needed for a 4K HPMN.
3. The overall bucket size of all collateral probably wouldn't grow much bigger than it is now, but if it did, dash would be more scarce and the unit price would go up.
4. This is my most important point. Some would say, a cheaper masternode does not increase distribution because the previous 1K holders simply switch to 250 dash x 4 nodes. But I disagree profusely. Over time, some people need to raise money for things like personal emergencies or to start a business. Selling a HPMN allows people to stay in the game with a masternode or two while raising capital. This is the compromise people want. It happens in the housing market all the time, such as selling 50% of your home equity while getting to live in it.
5. OG's get to participate in Platform, this is their reward for demonstrating diamond hands.
