It's only dumbass backwaters like the US that can't figure itself out because of the insane number of regulatory bodies they have...
You'll find similar numbers of regulatory bodies in any large developed economy or economic bloc. I know this because I work in the regulatory system.
they have to spend years working out what something is, so they can assign it to the appropriate department to be regulated..
That's how most models of democracy work, because the regulators are part of the administrative branch of government (that deliver the policies governments enact), and all the decisions need to be taken by the executive branch of government (politicians), and the policy mostly needs to be enacted by legislation. Those last two aspects require involving the legislature, and that's another unbelievably slow process.
Change in government is slow. If you want a faster and more responsive government then you need to remove secretaries of state and their juniors from the legislature, have two or three times as many of them, and have them working full time on policy without the oversight or challenge of the legislature. Even then, stuff takes time - you want to change the law, that means impact assessments, business and public consultations, drafting a consultation, then reviewing each and every response, then drafting and review of new or changed policy, drafting, review, passing of new legislation. Because everything government does has to be done with the full authority of government, things do take many times longer than an equivalent decision in the private sector. And if it involves new regulatory responsibilities, work is needed to decide who is the regulator, how the regulations will be enforced, etc etc.
It's very disappointing how poorly informed most people are about how democracy actually works.
