When you were born, your parents selected a name (usually one
that was not given to any siblings yet) and attached one of their
last names. They registered you with that combination, and this
is how you have been known for all your life.
Wouldn't it be eerie when, upon registration of your name, the
clerk had told you that all last names are coerced to that of an
industrial who is currently sponsoring a new highway project?
On today's Internet, this pattern is standard practice!
