What you're skipping over here is how that happens. If Iran wants to charge tolls on the strait, someone has to do something to keep Iran from doing that. And when you start gaming out the possible identities of that someone, the possible things of that something... well, the most likely route of this is via negotiating some concessions to Iran (i.e., at minimum sanctions relief and maybe even concrete progress to a nuclear bomb). That assumes that Trump even considers freedom of navigation as something worth concessions in the first place, which I don't take as a given.
