If I can tell which blocks are in the store just by starting the node, then anyone who seizes my hard drive can also tell which blocks are in the store. The only way to get around that would be to introduce some secret that I know but the person seizing my harddrive doesn't, ie a passphrase. Anything else is just pointless obfuscation.
