Unless your branch of libertarianism also gets rid of contracts, there are many scenarios where contracts between parties can and will affect you, and without the ability to petition the government for redress, you are screwed. Private parties are generally motivated by their own private interest -- we have democratic government at different levels to represent the interests of the people.

This kind of stuff happens every day between property owners. That's why we have things like zoning, permitting and environmental regulation. Nobody wants government intervention until their neighbor puts up a big ugly fence.

In my personal experience, I've been in disputes with government bureaucracy, and was able to get a reasonable resolution because we have elected representatives who care about constituent issues. I've also been party to disputes with large corporate bureaucracies, and your ability to push the needle as an individual is very limited.

If characterizing me as dishonest makes you feel good, go for it. But I'd return the favor by saying that like most libertarians, your position reflects an immature, self-centered and unsophisticated understanding of the world and how it works. I encourage you to take a few hours and study the history of how the negative outcomes of industrialization in 19th century America re-shaped societies thinking about regulation and property rights.
