People with heavy mental disabilities resort to smashing shit. Also the more people needlessly smash this stuff, the less of it is left. Look at how many classic cars were crushed and destroyed in the past and how rare they are now.
Many Plymouth Superbirds were worthless in 1970 and driven into the ground, or had their wings and nosecones torn off and thrown away. Now it's a half a million dollar car restored, and still costs more than a Ferrari Enzo as a beat up barn find. Same with the Tucker coupe, insurance companies called it "deadly and dangerous" and with nobody allowed to buy it, a lot of them got destroyed. Also a very costly car today.
On a smaller scale, same happens with vacuum cleaners. The more people needlessly destroy and throw out, that's one less that comes to market, shrinking the pool more and more. Then the price of remaining used ones climb higher and higher. Hell, the computer my parents bought when I was a kid, think I can try and buy that back today? It rarely comes up for sale. They all were scrapped because they were claimed to be "worthless".
Just flag those vids as terroristic acts or whatever that option is on youtube and hope for the best. YouTube rarely listens to video report flags, but after that incident with Jake Paul in Japan's suicide forest a week or two ago where youtube ignored the video report flags, maybe the bad press will get them to respond more to reports.
