Freedom of movement is actually a fairly good thing, though.
> EU regulations, but now without (sic) much reduced influence
You are misinformed, please read '1. "No Say"' of 'The Case For The EEA Option' [0]:
The next level of argument surrounding “no say” is that
despite not having a vote in EU institutions, EEA countries
have some ability to protect their own interests from EU law.
They retain a “right of reservation” - a veto - as set out in
Article 102 of the EEA agreement and thus have the right
to opt out of new EU legislation. This is a right that the
UK as an EU member does not have.
That is just a single point against the 'no say' argument. There is a lot more discussed within that article, including how influence is generally exerted "upstream".
> Under EU rules it will need to wait until it fully leaves before it can negotiate a CETA style trade agreement.
Yet preliminary talks over global trade are already happening.
Trade agreements can be agreed faster than the length of time it takes to agree big complex EU-style agreements anyway [1].
