Yeah, I find it amusing that the people who say that less government regulations will somehow make the corporations more powerful when it fact they are already controlling the government as we know it.
I'm not interested in a long conversation on this, but some food for thought:
There is pretty much no better example of right-wing libertarian governance (or lack thereof) than the early history of the settled West (or for instance, the illegally occupied Dakota territories prior to the US government buying them back from the Native Americans). The result? Business leaders did exactly what I said they would --they created private tyrannies. They were the owners of businesses, and generally they joined together for their class interests (inside of a town) and formed their own version of an everything-but-the-name municipal government. Everyone who wasn't a business owner was a wage slave in the truest sense, most women were prostitutes or outright sold into sexual slavery, children generally were forced into hard labor and had essentially no chance at an education, and therefore --totally unsurprisingly-- the concept of economic mobility (being able to, by hard work, move out of your station) was virtually non-existent. The system was largely limited to either bartering or making use of the US dollar (which means even they were still borrowing heavily from the US government to keep their economies afloat and stable, not to mention using the US military to prevent themselves from foreign, albeit not local, invaders). Additionally, the fought and killed each other quite often and murdering whole caravans and raping women was also exceedingly common (and there certainly wasn't anything to stop it).
We can also look at the next closest examples in US history of a purely right-wing libertarian ideology, would be the time surrounding the Industrial Revolution, which generated the exact same private tyrannies, monopolies, staggering income inequality, and labor practices were so fiercely unjust it lead people to literally creating gangs to fight business owners (e.g. Rockafeller's history is pretty damn interesting to read about; the man was the private dictator of his oil fiefdom, but the paragon of a Randian hero). People acted so poorly, that everyone was begging the government to get involved, which included business owners. And when business owners control all of the wealth and have safely secured all of the power (including distribution of information), they get whatever they want --it doesn't matter how you, as a libertarian, feel about that or what's written into previous law (it'll get overturned in a jiffy if the right people want it). So talking about "prohibiting business owners and corporations" from taking control of the government after squarely handing them all of the money, power, and influence is something I find to be wildly inconsistent --not at a logical level, just at a performative level. There's nothing stopping them from doing what time and time again in history they've proven they will do, namely buy off the government and remake it to their purposes. You can see this in the Koch Brothers, who love to talk about libertarianism, right up to the point when they get their huge government handouts (e.g. oil contracts and oil subsidies) and government services. Then, boy oh boy, they expect what they paid for.
I've always been curious --this doesn't give you a moment's pause in terms of your ideological commitments? It certainly gave me pause when I was a right-wing libertarian. Life is a lot less contradictory (and not needing logical gymnastics) as a left-wing libertarian. Or that's what I have found, at any rate.
