Maybe, but in the short run it could be disastrous for those who lose their jobs and livlihood as a result. We see what longterm harm and resentment the death of the mining (and other) industry bred in this country, many people snd communities have still not recovered, I think Brexit could wreak similar havoc on farming and the food industry, manufacturing and small business.
One has to decide, should we buy plentiful relatively cheap lamb from Australia and New Zealand after Brexit or pay more for the homegrown variety? The reality of it is that more people will be able to have lamb on their table more often so is that necessarily a bad thing? UK farmers must learn to produce good quality food at a reasonable price and not depend on subsidies amounting to around £100 per acre per annum.
Parliament has a moral obligation to deliver Brexit which after all is the will of the majority. Anything less would undermine democracy for centuries to come IMO.
