I think the part I may have misunderstood was where you said, "With Googles CDN, they have to hack either my website, or Googles CDN.", and I interpreted that as an exclusive condition, rather than an inclusive one. Probably the "either" that did that.
With that misunderstanding corrected, I believe you're generally correct on the security argument. There's still some plausible variation in terms of server security policy and implementation of things like intrusion detection, (Is it safer to keep all your money in your home, or is it safer to keep most of it in a safe deposit box in a bank?) but that's not the key problem I thought I noticed in your argument, and not one worth devoting energy into.
