If someone else was to take my screen name could i sue them for that

I mean....Its bad enough when every little thing in the real world gets caught up in courts but now the virtual world too :-/ I thought the internet was supposed to be a free place for everyone...Now you have to pay a yearly fee just to have a .com address on a personal website...For once can something be left as is without somebody taking it to the extreems :-/
I dont go to these little virtual worlds they speek of but who in their right mind would pay 30 grand for some virtual island

Just buy a version of FS...Theres a whole virtual world for you for .002% of the cost
