So why the %?$ don't eBay at least have their SSL certificates with their ownership in? I think the EV SSL certificate cost me $80 for a year, so hardly a fortune.

A wouldn't have thought the "ownership" carries any useful information. I presume it can be easily forged. As a colleague of mine, Stefek Zaba, used to tell everybody in the mid-late 90s, "my name is Donald Duck, and I have a digital certificate to prove it".

The only important part of a digital certificate is that it is vouched for by the chain of certificates to a trusted root certificate. If you trust the chain then you have (some) trust in the site.

Of course it isn't necessary to have a certificate that has a chain to a trusted root certificate. One system I worked on had a "self-signed" certificate, and that was completely sufficient for our purposes.
