Brexit is losing its point

I am coming to the conclusion that Brexit is becoming an irrelevancy. After the announcement by Gove - a leading Brexiter - of new UK food tariffs to replace the EUʼs, I am coming to the conclusion that Brexit is becoming an irrelevancy. What is the point of it?

The EU has been running four egregious trade and economic policies from its outset: CAP, VAT, the tariff barrier and the Euro (fortunately the UK avoided the latter, but the fact that it even exists is proof of the incompetence of those responsible for the those policies). It is becoming evident that the leading supporters of Brexit are intent on replacing the EU policies with home-grown versions of the same thing. It is as if a prisoner is told he is free, but remains in his cell, and is then required to pay for his food and lodging in the jail. Such a Brexit is all pain and no gain.

The ERG - this includes J Rees Mogg - and Economists for Brexit, should have raised their voices in protest when Gove announced his proposals for the tariffs, which have not been denied. Labour and the left should have raised voices in protest on the basis of their own principles. Economists for Brexit have not helped the case through their claim that British agriculture and manufacturing would be destroyed.

As regards agriculture, it appears that there has been no rigorous study, ie based on a Ricardian analysis, made on this subject, not by DEFRA, nor by any think tank, nor by any academic institution, nor even the National Farmers Union. Such studies as have been made are inadequate, since, like the ESRC one, rents are regarded as an input cost, or in the case of that by the NFU, rents and imputed rental incomes are rolled up into the category of farm profits. This is astonishing, considering that many universities, including Oxford, Cambridge, Newcastle, Reading and Bangor, have departments of agriculture and agricultural economics well equipped to crunch the numbers properly and predict what would happen if cheaper food from outside the EU became available.

If nobody in authority knows what to do with the freedom Brexit gives, and the EUʼs dysfunctional policies are replaced with UK versions of the same, what is the point of it?
