You should try reading that patent sometime before you claim it isn't reasonable.
It is profoundly dishonest to characterize patents using a trivial phrase like "one-click" and then pretend like that also means that the patent is itself trivial.
You think Barnes and Noble copied the novel implementation of one-click, as disclosed by the patent, and didn't use bog standard database and cookie techniques?
You cannot implement "one-click" using "bog standard database and cookie techniques".
Your idea of what this patent covers is incorrect. It is not a patent on the feature of "press a button to make a purchase and skip the checkout process" or "have a cookie so we know who you are".
I'll bite - what parts of the patent can't be done with bog-standard techniques? I took a look and it seems obvious in retrospect, though so many things do.

I know why you do it- it fits your ideology.
But it doesn't fit reality.
