Hmmm, some of these hypotheticals are wishful thinking.
For example 1, it's a double edged sword. As a seller, no international chargebacks sounds like a wet dream! As a buyer, why would I use bitcoin internationally when I can't reverse my transaction if they don't deliver?
Example 2 seems legit for now. If and when bitcoin becomes more mainstream, you'll see an increased transactional cost from overhead and risk mitigation, so the transactional savings will probably not always be there.
Since we don't gift each other bitcoins, Example 3 isn't a problem.
Example 4 is laughable because in the last week, four Bitcoin exchanges were hacked (or robbed by the owners - still TBD) and people who had their coins in those exchanges lost it all.
Skimming CC numbers is for sure an issue for credit cards, but as someone who has had their credit card skimmed, my issuer locked my account within 2 hours of fraudulent activity, called me, and eventually gave me my money back. How many Mt. Gox users got their money back?
