I agree for the most part. And in fact I've also come to think that the mysterious shortages we have seen even post pandemic, such as baby formula and bottled water (because of a supposed plastic shortage!) are also just for show. You might think that these are enabled and instigated to jack up the prices eventually when these things hit the shelves again. Note that they are all critical things that we need, mostly. I sometimes get the impression that Biden-Obama-Clinton-Bush New World Order controlled government agencies are using all kinds of sanctions and citations on these industries to create these temporary shortages... And that another possible motive besides price jacking is to say to the public: "hey, we control everything, get it?? If we don't like the kind of talk that we hear on the street this is what you're going to get."
Note that there wasn't a shortage of any other things that are packaged in plastic bottles. Just water, the most important one.
