It's slowness is it's most effective and insidious trait. It ingrains itself into a society, with promises of "this is healthy if we just let it be". Which is clearly not the case.

If most positives from it involve it having to be shackled entirely by regulation to constrain its most definable traits, it is not a good thing. It is just exploitable.

Yes, the right regulations, that will then be constantly clawed back again and again until no regulations exist once more. We had wonderful social services and financial and industry regulations in the past, but people who are greedy and don't want to help their neighbours work tirelessly to remove those services and protections until they no longer function and then remove them completely as "obsolete" because they were never allowed to actually work in the first place.

Capitalism is an inherently hierarchical system, and hierarchical systems fundamentally consolidate power to the top. This consolidation of power is a primary feature of the capitalist and state structures. You can't out regulate the nature of hierarchy, it will always adapt to the present conditions and find ways to consolidate power. A just and equitable society cannot exist under hierarchy. Humans are highly social and highly adaptable animals, there is no singular "human nature". What you've labeled human nature is the nature of capitalism and the state, not humans.

I'm not interested in slower consolidation, because at the end of the day that means someone else is going to have to deal with the consequences of it down the line. See Canada, the UK, Germany, and Sweden as examples of what will happen under "better regulated" capitalist systems. Things are ok for a generation or two, and then capital begins it's encroachment once again. They're closer to the path the US is on than any of them will readily admit. Why would I fight for half measures?
