Even if you need to insert your drivers license to the computer in order to access it, and every packet you send is signed with a user-specific hash, the only people it's going to matter to are the people who aren't doing anything wrong right now.
Cracking down is just going to create more crackers, and most of us in the middle probably won't really notice.
