There’s a difference between libertarians and republicans looking to make more money. Most of the supposedly anti-taxation anti-regulation billionaires just want less tax for them and fewer regulations for their business; everyone else and especially imported products can be taxed more to give the billionaire’s company more subsidies, and regulations to prevent competitors from growing or starting up is even more welcome. Even when it comes to personal freedoms, they don’t care and will gladly support the government in reducing those freedoms if it earns them some sway.

This all goes directly against the libertarian principles of government non-intervention in the free market and people’s personal lives, both of which are vastly more important than just reducing taxes, which supposedly comes as a side effect later (even if in reality taxes would probably stay the same as you’d need to provide more assistance to low income people)

This isn’t to say that more principled libertarians are necessarily noble or right or whatever compared to people who just want lower taxes, just that saying it’s about reducing taxes and giving power to corporations is buying in to the direction that corporations are trying to move the ideology in
