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.
