Very few patents are for actual original innovations that warrant a 21 year monopoly.
Wow, wrong fact right in the first sentence. All credibility: gone.
You don't get a 21 year monopoly, or even a "20 year monopoly" which is what you were probably thinking of. You get a monopoly that lasts between patent issuance and the end of a 20 year period starting from the earliest claimed priority date, plus any patent term adjustment (assuming the patent was filed after 1995; pre-1995 is a little different).
So you're wrong right out of the gate, then, yup, a bunch of anti-patent blathering. And modded up as informative. Good to see
