it doesn't.  it's just not a generally-applicable mechanism. 

subject to relataively few constraints, you own 'danisch.de' for as long as
you renew it.  most users do not own their IP addresses.  in order for routing
to scale (at least with current routing protocols), it is necessary that
networks be renumbered from time to time.  so we do not want to encourage
tight binding of IP addresses to domain names even for those cases where it might
work, for now.  also, source addresses can sometimes be forged, so we don't
want to rely on them as authentiation tokens.
