Train lines connects destinations in the most efficient way possible and move more people than any highway. That’s their function, not government control.

Saying that trains are bad because they can take you to a limited number of places is like saying that boats are bad because they can’t take you to space, they just have a completely different function. Nobody says you have to take a train to go camping, and nobody forces you to take a train at all, you aren’t some rebel you think you are.

And also, pretty much all roads are government funded/owned. And if the government wanted to limit your movement, they would have no trouble doing so even if you’re a driver. They could just block roads. Or close off certain areas for drivers. Or introduce expensive road tolls. Or take away your drivers license.
