I do actually but it is up to the person. The main reason for me to encourage it is that if knowledge is reserved for the high priests it will eventually be lost. How many civilizations did we build by now? No one knows! We haven't the records. The stuff people must have figured out. Of course may would pretend it wasn't a big deal but all those deleted forums had plenty of insights to offer. Practical ones and historically valuable.
The real value of knowledge doesn't change if you duplicate it or make it widely available. On the long term, blocking access and rent seeking doesn't create value, it destroys it. It seems useful for the individual who wants to pay their bills or for the one with insatiable greed but in the end it will makes us stupid.
For example: I would like a high quality UV-B lamp that isn't INSANELY expensive. They are pretty ordinary lamps but developing the coating is very expensive. The work has been done tho, lots of times, over and over again. Most results are just bad.
About 35% of the US and about 1 billion globally have vitamin D deficiency, 50% has an insufficiency: Fatigue, Not sleeping well, Bone pain or achiness, Depression or feelings of sadness, Hair loss, Muscle weakness, Loss of appetite, Getting sick more easily, etc
Great loss of economic productivity or more opportunity for me? You decide!
