I don't think EFTA was ever a possibility, BigChoc because of Conservative Party dynamics.
EFTA was over when May went with her 'red lines' (to the amazement of her own negotiating team).
Rory Stewart has talked about his own amazement that May didn't start with a soft Brexit position - but she knew her Party - & she knew it was dead before it breathed.
That's the problem with Brexit: there is no path to any kind of rational outcome or compromise because so many of the pieces just won't fit together.
And always, always we come back to the question as to why May pressed the red button on A50.
It was such a very un-UK way of doing it. Committees and reports ... that's the UK way. Or was.
But a madness was in the air.
And no-one was there to fight the madness.
It's wearing off now, thank God.
Most people are calmer. Not all. But most.
Alas, the main Parties are still in the fall-out, bearing the marks of the madness.
But you can feel it: the craziness is receding.
