One of the basic points of pseudovelocity is that you don't need to break momentum conservation, because pseudovelocity moves you without actually involving momentum.

EDIT: Which actually gives me the thought that 'inertialess' technology along the lines of the Lensman books might give you results usefully similar to pseudovelocity without actually using reactionless drives.
