True, although I’ve also read that only a very small fraction of the internet is used for these day-to-day operations; the rest is utilised by “dark web” type activity (not all nefarious). So perhaps ‘the net’ is much larger than it actually has to be, but that’s kind of like arguing there are too many books and libraries, so…
As for the value of the stock market, I can only say that perhaps the most valuable business deal in US history was a private equity deal (no, it wasn’t PTON).
