They aren't "random pieces of material". They are strips of polyethylene that, in the case of Mr. Tuffys have smooth edges and smooth ends. Other attempts at making the same kind of strip haven't worked as well in my experience, however. Slime's version has ends that are too thick and are sharp enough to cut through the tube in just a few miles. I've never had a problem with them.
They work well enough that many tire manufacturers put the liner under the tread. It's the same material.
"Thorn proof" inner tubes are just heavy. I'd rather use Slime...and I hate Slime!

Seven years...what a newb?
I've been using them for more than 25 years in the heart of goathead country. I've been on a ride with 3 other people where we had 27 flats between us. One poor person got 20, the guy running tubeless had 6, my wife had one (in the tire I forgot to put the Tuffys back in) and I got none...with Tuffys in both tires.
Don't get me wrong, I can get, and still do, get flats but the Tuffys slow them down.
