Issuing a license is a form of "using it" in a use it or lose it scenario.
Those are not patent troll companies.
Patent troll companies file patents and then sit on the patent until they can sue another party for infringement, and never make an attempt to commercialize their patent.
Another example of not using it in the use it or lose it scenario is Pfizer's acquisition of Esperion Therapeutics in 2004. Esperion was developing a competitor to Lipitor, so Pfizer purchased Esperion for $1.3BB and shelved the technology to prevent competition with their best selling drug. Had Pfizer "lost" their patent for failing to commercial Esperion's drug, that drug could have entered the market as a generic to compete with Lipitor and severely reduced the cost of statin drugs for consumers.

Many of the patents asserted by trolls were not actually filed by the trolls. Most often the troll company simply purchased the patent from the original owner (or, often, a bankruptcy court) and then they proceed to go about suing others using their newly acquired weapon.
Worse yet, the troll company was often created for the purpose of owning that specific group of patents. That limits the damage from a lawsuit gone wrong to just that group of patents, and not the many other patents owned by the hundreds of other similar troll companies that the same lawyer runs.
We really need a patent troll version of anti-SLAPP laws. To go past the shell company, and hit the people who run them.
That is hard I think, as there are patents that are not licenced because no one wants to - but I think every holder of a patent must licence it to any party interested. So just "sitting on patents" is not really possible to my knowledge. (but I am really not an expert here)
This is Qualcomm's big business (and others), getting their patents into standards like 5G and then charging people a fair amount to use it - and they have to license it to everyone, even their arch nemesis. Or you just buy their chips.
For a patent of something you invented, but did not submit to become part of a standards-body, you absolutely can choose not to license it for any amount of money.
If I'm understanding what you're saying correctly, then I'm not sure where you got that idea.
Patent holders are not required to license their patents last time I checked. You are simply required to acquire a license prior to using patented technology.
If they don't want to license it, you're SOL.
(edit: if you were speculating on what should be, and not what is, then my bad... :)
