Capitalism doesn't thrive when the government agencies we DO maintain become corrupted by the special interests groups and corporate lobbying that our current model of capitalism allows to run roughshod over everything.

I mean, unless every citizen is going to become a full-blown citizen-scientist and become proficient in all the sciences I don't see how we can maintain a nation this size without some agencies doing routine food inspections and water quality testing.

NOW...

The agencies we currently have in place are NOT up my standard in any of those regards and don't appear to be working the the interest of the People, so it would take a complete overhaul.

We'd all like to think our neighbor Farmer Joe isn't going to let chemical waste run off of his farm and contaminate our drinking water and kill our family but...

We tried that and it turns out it's human nature to try to get away with anything you can so long as no one is there to call you on it.
