I know how websites work too, been doing it for 12 years which constitutes more than half of my lifetime. I'm not really sure what you're trying to say here.
The fact is, people can and DO mistake websites because of the domain name. Domain names are very important and a huge contributor to the amount of traffic a website can potentially receive as well as having an impact on peoples' perception of the brand/identity.
There are laws against sniping domains of registered trademarks and such, but I'm really not sure how that works when it spills into the personal name area.
