Why bother with LFTR when coal is cheaper? Coal is cheaper than regular nuclear too.
When we run out of coal and natural gas and oil... then business will invest in new things.
No market failure, this is the market working to bring you stuff as cost effectively as possible - unlike government that doesn't care about cost and will reduce your standard of living for pipe dreams. Most voters aren't even aware of things like capital cost when supporting these pipe dreams, and their representatives pander to their ignorance.

Go to Youtube and search LFTR. Watch about 6 hours of the videos that are available.
Then go to this site:

and read as much of the documentation as you can muster.
Then come back to me and explain why the "Free Market" or "Private Enterprise" or "Free Enterprise" hasn't been able to build another one of these, after the prototype, in the past 40-ish years.
You can do that after you admit that the technology also solely exists because of Government funded research to begin with.
sighs.
Short sighted market operation bringing you the most cost effective solutions while externalizing the cost of anything and everything that can possibly be externalized.
In other words. Business has a narrow focus and any resultant costs from their operation that are not immediately realized and easily avoided will be avoided.
The market is not without serious flaws.
