The problem is this
"Politically, many hurdles exist, including the need for existing Efta members to accept the UK’s application, "
They have already indicated we are not welcome and have a Veto
And it is still only a Fudge and unacceptable on the grounds of none of the advantages of membership of the EU on the rights, working conditions, and the Environment we currently have.
It would still leave us under the authority of an unfettered UK parliament who you can be sure have only their own interests at heart, at the expense of the public.
Just look at the way they changed sides over Brexit, and will again if it goes wrong.
Sorry but fudging things to keep the Brexit insanity going is unacceptable and always will be, and always work against the rights and future of the population, favouring the parasitic Political Elite and their Paymasters that runs this shambles of a country.
It will never achieve the Dream of a better life that people who voted for it are expecting, and no one will actually say anything more encouraging that make vague promises that things will be better after 10 years or so, which is fantastic as instantly advantageous results were promised at the time of the Referendum, and ALL promises made then have proven to be lies.
Brexit isn't even a Gamble, it's a proven loser already, like placing a bet on the last race putting your money on the horse that came in riderless after the others got back to the stables.
