Which of these points matches one of Wilson’s proposals to avoid future wars? adding barriers to trade encouraging nations to arm themselves declaring freedom of the seas allowing secret treaties

Declaring freedom of the seas.

Explanation:

Freedom of the seas is one of Wilson's Fourteen Points, according to which the open sea is free for all and no state can hold sovereignty on it.  So in the high seas freedom of navigation applies, as well as free fishing, and the only state that can exercise control over a ship is the very state whose flag the ship is carrying.  

This principle sought to avoid international conflicts by declaring ocean waters as international, therefore neutral and not belonging to any state, with which no state could attempt to conflict with another for issues related to the high seas, which at the time was the main transport channel for people and goods in the world.
