Like Jim K mentioned, there is a USDA program to do just that. We did it for years as a family adventure in one of the national forests. A few rules about how big the trees can be, and a $5 permit if I remember correctly. Pretty much impossible to find a forest tree that looks like a Christmas tree, but by taking some of the over thick little ones out, it helps the big ones, and in a tiny way, decreases fire risk. One year we even found a bull elk skeleton, rangers let us keep the skull, he hangs in my woodshop, kids named him Carlos.
I don't see anything wrong with the commercial I guess. Now that a one they did several years ago with the guy pounding wood fenceposts in with a sledgehammer, that one infuriates me.
