Is the lack of an inexpensive falling block option due to lack of demand or something else?

The falling block action has always been interesting to me and while there are some very notable examples of it in contemporary use (Ruger No. 1 and 3) you really don't see it outside those and some reproductions, all of which can be eye wateringly expensive.

The action seems simplistic enough that it would lend itself well to a less expensive price point but, as far as I'm aware, that hasn't been acted on by anybody. Single shot rifles are legal in virtually all 50 states so the idea of a simple to machine, 50 state legal, single shot rifle would seem to be obvious.

Is it just that bolt actions are even easier to manufacture? Are they just more well known and popular? Or is this just a route that no one has really seen fit to go down yet?
