Gold ownership doesn't mean having to carry around the gold, just having some evidence that you own it.
If you are talking about some sort of bond or note backed by gold, well there is nothing stopping one from doing the same with bitcoin. A company that holds bitcoins can take your info and provide you with an "IOU x bitcoins". So we'll call it a tie in that scenario. Now if you want the security of personally owning your bitcoins(keys), then yes, if you lose them... they are lost... same for gold. <snark>Of course you could pull out your backup of you gold you had in another location</snark>
I'm sure there are many properties in which gold would win, but I still see no added convenience to owning gold as opposed to bitcoin. Using gold for something other that trading in some sort of market/exchange would require carrying it around. Go into a store with a gold note and try spend it. Doubt there will be many takers, (remeber... you can just go to the issuer with your id and get a new record) though I'm sure you could find a few fools. There might be a few more that would take government issued golds coins... a quick search on the internet could provide enough of a value to reach an agreement. However you have to carry the coin and protective sleeve and it's not divisible. Random bullion though? Doubt they are going to take the time or have the equipment to verify the weight and purity. Not that you are going to find many places taking bitcoin at the moment, but it takes little more expertise or equipment than current payment solutions take. If it's a large sum of money you would need to let some time pass for several blocks to verify the transaction, but that's still much easier. Buying something from an online shop? I don't care how hard you push your gold bar into the ethernet cable... it's not going in and come out the other end.
