I know some countries do not allow people to buy gold and in Greece they wanted to stop people from buying it too, when things got tough. It might be seen as a safe haven, but it has some regulatory issues too. ^hmmm^
It doesn't matter that you have the right to own it or not. You can always hide it somewhere and the worth of the god will still be good especially in other countries!
What is the value of that, if you cannot use it in open trade? The problem with transporting it to other countries where it has value, is the logistics and the weight. If ownership of gold is forbidden, you cannot simply climb on board of a jet with a bunch of gold bars and wizz to another country. The security at the airport will confiscate all gold before you can take it out of the country. Bitcoin can go through borders without any trouble and that is a mayor advantage over gold.
Bitcoin is a bit volatile at the moment but once it gets more distributed, it would be a perfect alternative for gold ownership.
Well, Kakmakr, I have the following comments to pass along:
1) It is rather easy to take small amounts (say 2 oz or less in small coins) with you through the airport. Be creative...
2) "There is always someone around who will take (= accept as payment) your gold."
3) Yup, BTC goes through airports very nicely! The problem is that BTC is not popular in many countries (like Peru: my "other" beat).
4) You wrote (re Bitcoin):
"... it would be a perfect alternative for gold ownership."
I would correct that to:
"... it would be a perfect complement to gold ownership."
