I don't have to prove ownership of my bike and unless someone else has proof that it's theirs (including serial number) nobody is taking my bike from me. Likewise my watch, my phone or whatever.
That said, I use www.immobilise.com to register the serial numbers of my bikes, watches, laptops, tablets, tv's and so on. This however is more for insurance purposes in the event of theft.
