@lanodan That and a place to move to (if we are talking about geographical locations). That Wikipedia article mentions The Free State Project which encourages libertarians to move to a single location (New Hampshire) to make it move align with their principles. There are also a lot of various seasteading and micronation projects, but it seems like only right-libertarians are embracing them.
The Internet makes it somewhat easier to find like-minded people. If it's just in your local area, you could just pass out fliers or place ads on builtin boards and power lines. You'd be surprised to see how many people are like-minded they are just aren't bold enough to speak out.
@lanodan
I don't feel like that would change anything. That feels more like a glorified petition (which itself is just a glorified suggestion).
Wikipedia only gave The Free State Project as an example. Though personally I like the idea of having smaller jurisdictions where people can just move to a different location if they don't like the laws, culture, etc.
That said I do wish to remove electoral sud-boundaries to make gerrymandering obsolete and I think one of the ways is to effectively support a politician rather than elect one.
