Dramatics like you've posted are the core of the issue. Clearly most people did vote for that - business views were taken into account as part of the original vote; same as anyone else. Only 4% of business actually does any international exports.
As indicated, when you import so much more than export, tariffs aren't really an issue.

Unfortunately 'crash out' is really just proper leaving without our own preparation. We could start preparing now, but I agree with you that because we didn't prepare for the main event that there would now be increased chaos - primarily because the EU wouldn't show any pragmatism, because they are annoyed we don't want to pay their bills and remain uncompetitive, which is really what the EU is about (following the French model).

Medicines are currently regulated by a shared agency. All the staff were in the UK and as we were a net contributor, it would not have cost us anything to just keep all the staff as the new UK agency. In fact if we had wanted to, we could simply have just used any drugs authorised by the EU without paying for the medicines to be checked ourselves - it would be our choice, and no more risky than present.
It would be valuable to cooperate on these things, but we don't have to have the same rules. It helps, because the same products can be sold everywhere, but if we want something to happen for a reason we currently cannot.
The UK is very good at big pharma. We would have no problem with medicines, and could import easily from outside the EU.
The UK could also choose outside the EU whether to remove patents from medicines that were seen as too expensive. It would be unlikely as we have a strong industry to protect, but that would be our choice in the future.
The only reason prices would increase is because of double testing. It's our choice whether to do that or we could just free-load off the EU list as well. It should be clear that many developing countries get exactly the same grade of medicine as the EU, but do not individually test them - but if they wanted a different standard they could.
Nobody is suggesting the UK and EU could not cooperate, but with EU style cooperation there is always unnecessary obligations such as if you want to test medicines together, then you must only ever use medicines we have all agreed. A better approach would be, we all join to pay together, and then choose what each country wants to do - its like a non-uniform day, it most cases people do the same and wear jeans.
