What I'm proposing is a huge change, but also comes with caveats. If the content or the people it brings provide value, that value can be redirected to layer 2 with more flexibility for those particular communities to create the culture they want to see.
There would also have to be a long period of acclimation, doing anything at the flip of a switch would be devastating to those who built here. There are others here already building the tools to make things like this possible, and with the right approach, things would be conducive to growth and synergy.
You of all people know how incentives can make or break an ecosystem. Right now the incentives are obvious, what I'm proposing only exists in the abstract, but if we proceed with respect for people's wants and needs, the proper incentives can be incubated to ensure little to nothing is lost, while much can be gained.
