MB,
You paint a much too rosy picture re the scenario for imported gas. You are forgetting the spiralling interest bill attached to the extra foreign payments that importing gas supplies implies.
Not only are UK tax receipts forgone...income tax from jobs, petroleum tax and corporate tax..BUT it also impacts on the current account deficit & net foreign debt. This rising interest bill to service debt has huge implications for residents. Particularly given the UK is running a massive Govt debt ~ 1.8 trillion GBP (86% of GDP) and current account deficit ~ 20 billion GBP Q2 2018.
And when Brexit is implemented and these figures ratchet up by x%....Armageddon for government services, jobs, taxes etc
Refracktion can likely advise a solution to this....
