Quote Section 1B.01:
The Manual on Uniform Traffic Control Devices for Streets and Highways (MUTCD) is incorporated by reference in 23 Code of Federal Regulations (CFR), Part 655, Subpart F and shall be recognized as the national standard for all traffic control devices installed on any street, highway, bikeway, or site roadway open to public travel (see definition in Section 1C.02) in accordance with 23 U.S.C. 109(d) and 402(a).
In accordance with 23 CFR 655.603(a), the MUTCD shall apply to all of the following types of facilities:
A. Any street, roadway, or bikeway open to public travel, either publicly or privately owned;
B. Streets and roadways on sites that are off the public right-of-way that are open to public travel without full-time access restrictions. Examples include roadways within shopping centers, office parks, airports, sports arenas, other similar business and/or recreation facilities, governmental office complexes, schools, universities, recreational parks, and other similar publicly-owned complexes and/or recreation facilities. The above-described examples of streets and roadways are referred to in this Manual as site roadways open to public travel;
C. Publicly-owned toll roads, including those under the jurisdiction of a public agency, public authority, or public-private partnership;
D. Privately-owned toll roads where the public is allowed to travel without access restriction. This includes gated toll roads or roadways where the general public is able to pay to access the facility; and
E. Grade crossings of publicly-owned roadways with railroads or light rail transit.
The MUTCD shall not apply to the following types of facilities:
A. Roadways within private gated properties where access to the general public is restricted at all times;
B. Grade crossings of privately-owned roadways with railroads; and
C. Parking areas, including the driving aisles within those parking areas, that are either publicly or privately owned.

The short answer is: Money. No compliance, no federal improvement project money.

I think you don't grasp the costs of things, especially when government and "safety" are involved. The "Big Green Signs" over the interstate that tell you how many miles away your exit is, or which lane to be in for a particular exit, those alone are tens of thousands of dollars (depending on how many signs/panels each one actually needs and whether they're free standing or attached to another structure such as a bridge). The fancy, permanent, variable message signs are going to probably start at 50K and could easily be over three times that.
As newer ones are LED-based, they don't take that much power to operate. Whether they need to operate continuously or only when critically needed is a separate argument that can be had. But there is also an ongoing cost for maintenance, testing, and then the people that actually configure and operate them.
But, waste of money? Every situation is different. I remember as a child in the early 80s there were smaller versions of these around, and they all disappeared by the mid 90s. Nowadays, bigger fancier versions are all over roads (literally) everywhere. They can provide critical timely information for drivers, such as suggesting to exit because there's a huge accident ahead, or that the road is closed, or something else unexpected and unanticipated awaits. I imagine some of these installations are more-useful for this purpose than others. The ones not as usual would be a waste of money.
