But that's true of almost every industry. Your bank advertises that you can withdraw your money at any time, but if everybody withdrew their money simultaneously there would be issues. A store advertises next-day shipping, but if everybody ordered simultaneously there would be issues. A house might have 100A power service, but if every house started burning 100A simultaneously there would be issues.
Put another way, what you're proposing is dramatically slower speeds for most users. ISPs are profitable, but they're not that profitable. Actual average usage on most lines is probably low single digit percentages, if not sub-1%. I just checked my line - my average use is about 200kB/s (for a total of about 500GB per month), or about 1% of my speed cap.
