Note: Protecting the businesses and people doesn't necessarily mean protecting the current status quo. It can also involve establishing and funding support systems for the people and businesses affected with transitions where possible. Establish more-generous welfare packages for those who lose their jobs, stimulus packages to support businesses, retraining systems for those whose careers are no longer viable, state sponsored establishment of new businesses to replace ones that prove no longer viable. A heck of a lot of money a conservative party would never spend, but it's what I'd call a responsible approach and probably a good test run for the inevitable waves of automation-related layoffs over the next few decades (and probably should have been in place already since the digital revolution has already long begun but heyo).
Hence why I specifically mentioned protecting the people in the jobs. That's the priority. If the only path to protect them is to protect business, you protect business. If there's an alternative route that protects them, sure let's try and convince people we should take that.
So far I've yet to see any serious proposals from pro-Brexit people for those alternate routes, mostly because they refuse to engage with the idea that anything could need doing and it won't be all rainbow farts and unicorn piss in the first place. Brexit is treated as the goal worth any price, instead of the means to achieve something. That's just dangerous.
Wanting to take the road of, to put it bluntly, "It's gonna be disruption so fuck everyone who doesn't want that" is just...something I have a lot of words for, most of them either synonyms of "self-centred" or rhyme with "Seeing a Jeremy Hunt".
Plus there's that a good chunk of the more at risk of losing out businesses are the ones that a sensible modern government would want to be encouraging the growth of. The modern world is a world of services. Which are more at risk from losing out here. I occasionally have to work with Americans on services (IT is seen as global so we're all in one team), it's honestly frustrating and inefficient simply because you only have a few hours of the day in which both of you are awake. You need to touch as little of the same stuff as possible to get anything done, and that just isn't anywhere near as efficient as being able to have constant conversations throughout the day as needed. You have to stop working on something and wait for the Americans to wake up, deal with it. Then after you go to bed they will have to do the same. It's a significant increase in time and decrease in efficiency. Efficiency is king for competitiveness.
The closer a timezone the better for co-operation, which is why the overwhelming majority of our clients and suppliers are either UK or EU. Good thing our business doesn't have any people in Australia, since such work with Australians would be a true nightmare unless one of us became nocturnal.
Also, the peoples wants are currently somewhere around "no no no no" to everything, you could say that the people are actually pretty well represented in parliament at the moment to be honest. None of the individual options have reliably scored over 50% in any of the polling. Summing up all the leave options together gets you a little over 50%, but as soon as you get into detail you get back into the problem of no clear majority again. You can't just take the majority of the majority, which then is a minority, and call it a day (especially when remain still outnumbers no deal when you do that). If anything it's become even more entrenched and divided since after the referendum, with even less people willing to accept one of the compromise options compared to the one they want in the polls compared to previously.
