fathom, I get what you are saying, but I don't think you quite understand what is being said.
IF you can purchase links (you being anyone with a website) and point those links at yourself and cause harm then ANYONE can purchase those links and point them to ANYONE and cause harm.
Google cannot know who purchased those links and with what intent.
I know of people who have done exactly this. I don't condone it, but if you've been in this business long enough, you meet both white and black hats. It works, it happens, it happens more than most would realize and now it's gotten easier.
