Wrong again Bob. With sidechains, native Bitcoin is available to anyone who wants to pay what it's worth.
That is the opposite of true.
The price of native Bitcoin transactions will be artificially fixed above their free market price because there is a production quota.
What you want is to model the ubiquitous welfare state structure that abound with plebs being subsidized by powerful institutions who leverage economies of scale to drop their own costs while milking the herd for different kinds of value streams.
Again, what you're saying is the opposite of true.
What I want is for transaction processing to be a competitive open market. That means let the market decide how many transactions to put on the blockchain instead of smugly asserting that most of humanity "doesn't need" that level of security and therefore will be forbidden from having it.
There are problems with the P2P network lacking price discovery, and as a result use of the blockchain creates externalities.
The correct response to that kind of problem, however, is not more central planning - it's more price discovery so that all costs are reflected in the price of using the network.
