|I very much doubt you would get anyone's ip address off youtube, they are connected to youtube so they will have it, but they don't just give these things out.|
Next problem: A good deal of people that connect to the internet use dynamic ip addresses supplied by their isp. It might be their ip today but with one power cycle of the modem(or perhaps the renewing the lease), it probably won't be tomorrow.
Unless you have some serious connections, even if you did get his ip you may narrow it down to *maybe* his city and isp. Next dead end: isp's don't just give out info on customers with the exception of law enforcement agencies(basically the same as youtube).
Even if you did find out all of this info what exactly would you do with it? Anyway there is a good chance this person is in some part of the world you couldn't or wouldn't bother going to.
