There's a reason we don't just "let the builders build". We used to do that (certainly to a massively greater extent than we do now), and the result was that although a few of them managed to construct monuments we can all be proud of, most of them built a pile of crap and/or damaged the places they built in and the people they nominally built for. This is true of literal buildings, but it's also true of a great many…
By arguing in favour of regulation, you have a set of assumptions and expectations that support your view. For example, in the literal case of buildings, you might be thinking of rent-seekers and greedy fly-by-nights that build low cost housing in high rises that collapse years later (for example).
I could argue, these were never builders to begin with. They are copying something (very unoriginal) which doesn’t count as building, but is rather a very good example of entropy (of an initial good idea perhaps).
Those builders who really build, as in create, they are precious and rare, and only bloom in an environment of less regulation.
It is one of those many contradiction in life where you have to let the failures through to allow for something new and novel to emerge.
I believe that we owe our own existence to this principle, where evolution was a very wasteful process of many dead ends in terms of life forms that emerged from it but could not persist.
If evolution had been “conservative” I guarantee you intelligent life would not have emerged.
Transfer this principle to the evolution of ideas, or rather, creations, we will also stagnate ourselves into a dead end with our civilisation if the “regulators” ever get the upper hand.
(I am not saying they don’t have a purpose or should not exist; merely that they need to be balanced by the ‘chaotic creators’)
