Your very last phrase there is the key one, Kevin. Very few MPs will have the guts to vote against brexit in the House even though most of them supported remain and know full well what a catastrophe faces us. They would lose their seats in droves and UKIP would have a field day. If the Supreme Court upholds the High Court and it comes to a vote, just observe the spectacle of a huge flock of turkeys all voting for Christmas. There really is very little room left for vision and principled judgement in all this. As Cameron had been so certain he'd win the vote, I'll have to put that down to unintended consequences.
