What would freedom of navigation look like in space?

What would a freedom-of-navigation cruise look like in space, and would control of a planet give control of its solar system?

It depends on how travel works. Slow voyages constrain routes and supplies, wormholes create chokepoints, and point-to-point travel can make access to refueling stops the central issue.

Navigation rights depend on the mechanics of travel in these hypothetical settings. In a twenty-five-year voyage to Alpha Centauri, a detour adds years and supplies constrain the route. Practical wormholes would instead create chokepoints whose owners could exclude unfriendly traffic. Point-to-point travel shifts attention toward the need to stop for fuel, including a possible distinction between protected inner planets and accessible gas giants. The physical parameters are unknown, so the alternative arrangements remain hypothetical.
