The regulation argument seems weak to me for two reasons: 1. As the article itself notes, the UK may not be the heaviest regulated now but for much of the 20th century it was regulated into abject poverty by post-war socialist governments, a problem that took 10 years of Thatcher to fix (i.e. wasn't really fixed until start of the 90s) and arguably the UK is still very far from a liberally regulated state. 2. By the time the underlying problem was fixed the steady growth of the EU and transfer of powers meant that the UK was unable to really deregulate relative to its peers to any meaningful extent. The article claims the UK is less regulated than other places in the EU but this can only be a small difference because such a vast quantity of regulation came from the EU Commission directly and had to be implemented regardless of the wishes of the local governments. So if you think that regulation retards growth, the article doesn't really argue against this belief, because going from really bad to about average will necessarily still leave you lagging behind where you could have been. This will unfortunately take a long time to fix. Brexit is an enabler, but the UK population has been subjected to decades of pro-regulation propaganda by the EU and plenty of people believe that things like GDPR or cookie laws actually are beneficial, evidence of European moral superiority and totally worth the cost. It would be easy to find Americans who describe the torrent of this sort of regulation as wealth destroying and ineffective bureaucracy, but such people are much rarer in British culture. I'm optimistic about the UK's future, however. Brexit does mean now that the UK can have meaningful debates about quality and quantity of regulation, a debate that was rendered entirely moot whilst in the EU as the EU doesn't do political debate of any kind, and has a deeply embedded culture of regulatory mass-production. With real deregulation on the table again, the UK can in theory begin to catch up with the USA. Especially true because the USA seems to be slowly losing its cultural bias towards free enterprise. Whether the UK actually seizes this opportunity or not is whole other question - the current Conservative government is not especially libertarian and just destroyed the economy through lockdowns. On the other hand, it is strongly incentivised to demonstrate the benefits of Brexit, and just had a 'big win' in the deregulatory space through vaccine policy. So it could go either way.
