Nice article,
How about the following.
We could have spaces conveniently placed, developed by the state, where people can sell what they can create at home or access where ever.
These need not be expensive to generate as all that is required, in its most basic iteration, would be parking and basic structures from which to peddle ones wares.

So that I can make what ever I can at home and easily go and sell it.
or with my vehicle go to the big market and sell the produce at the local market.

The big retailers of our world may not like it, but I am sure they could adapt and anyway the system is supposed to be based on the idea, of open entry to the market.

Instead of having metro cops harassing people trying to sell goods, they should be facilitated.

This could in turn generate production hubs.

We need to start by coming up with practical measures that can be introduced tomorrow.
