i am saying that pr is a metric which is used to sell links

I haven't seen any website that says "We sell links here". AFAIK it is the link buyers who approach websites and many of the buyers approach them based on their PR...So, are you worried that people aren't able to buy links cheaper as the sellers demand more money showing of their PR? :)
