The "advantage" that the LFTR doesn't produce fissile material was probably considered a disadvantage by most governments, at least until about a decade ago. Now that we have decades of experience with light water reactors it simply is a challenge to propose a solution that unproven on a commercial scale. It may look good on paper but it would be a multi-billion dollar project with multi-billion dollar risks. Visionary politicians who would want to take such risks are in short supply.
