I agree. Every pound spent locally massively benefits society.

If good shops are available people will use them.

I think we need the government to look at how retail works and what shoppers actually want.

There's not much local shops can do about the long tail but we need to stop penalising them and allowing online retailers to compete on tax avoidance.

From a systems dynamics point of view this is unstable as defectors still enjoy the benefits of nice enviroments while paying non of the costs (e.g. go window shop and try things on for size, then by the stuff from a low cost dropshipper).

So unless your "convicing" is a serious eufimism for fairy drastic emforcement, the plan is doomed.

If that worked, then why are we here?

The preconditions to the type of homogenious high trust environment that is required for this to scale is very fictional at the moment. But I would commend you for trying.
