> They very well could pull you over, revoke your license, and forbid you from driving.... If you were driving on their land or driving their car.

That is not true. They can say, "You are trespassing. Leave now." (Just as anyone can if you are on their land.) They can't take away a state-issued license. I'm not sure why you think it's so terrible that someone who lets you use their car can also stop letting you use their car. Likewise, you can do the same if anyone is using your car.

> They can reassign you to do something else or simply lay you off with a short notice.

And I can leave for another job with short or no notice. I can use a job to learn certain skills, then immediately go work at another company.

> Companies can put you in prison using the state.

Only if the state determines that you've committed a crime. And anyone can do this, not just companies. In this case the power is with the state, not the companies.

> Companies can and do extort workers on certain terms like withholding paychecks and so on.

That's mostly not true. If you are employed at a company and they don't pay you, they've opened themselves to a lawsuit. If you quit or are fired, in some states companies can withhold the last paycheck for a limited amount of time. Usually this can only be done to encourage former employees to return company equipment.

Even without government laws enforcing these things, if a company becomes known for such behavior they'll have a harder time attracting talent.

> Companies absolutely enslave people by for instance telling them a myriad of ways in which they can and can not conduct their lives.

In slavery you're not allowed to leave. If your employer wants you to do something, you are free to say, "Go fuck yourself." and find another. Contrast this to say… jury duty, where you can be fined and imprisoned for not doing what the state orders you to do.

> Her argument is that companies are communist dictatorships and they are all communist dictatorships, so you can not escape their control no matter who you are working for. Considering that you spend most of your life under control of such governments either one or another, these governments determine most of your life.

I understand her argument, and the reason it is incorrect is because unlike governments, the cost to switch companies is tiny. Most employment is terminated at the volition of the employee, not the employer.[1] If twice as many people are quitting their jobs than are fired or laid off, how can it be that people are in thrall to their employers? Wouldn't the ratio be the opposite if that were the case? Again, the cost of switching jobs is lower than the cost of moving between states. If you think we have freedom of movement in the US, then we clearly aren't subjects in company dictatorships.

I work at my current job because it's the best one I've found. That's true for pretty much everyone who is employed. Workers compete for jobs and employers compete for workers. Neither side can coerce the other. This is not at all like governments. With governments, you're mostly stuck with the one you're born into. There are only a few specific, difficult ways to switch governments, and at every step there is coercion.
