But people won't stop themselves. From a user's point of view: yes, you should stop yourself, but that takes effort to remember to read the article first. From pg's point of view (as this argument goes): no matter how many times you ask, people will still vote without reading the article, so if you don't want people to do so, the website needs to prevent them from doing so.
Your argument could be made for many features, like "please don't downvote comments before you have 500 karma", or "rather than protect against SQL injection, I'll ask the users not to do so".
Besides, this could be a way to detect accounts that are votebots -- why would they click on the article unless they know that you're tracking it?
A downside to this change would be that sometimes I'll read an article somewhere else first, and then see it here. I don't always re-open it before voting; I don't think this behavior is bad.
