BitCoin might be taken more seriously if their advocates explained why any of those need to be solved, and how BitCoin does it better than the existing solutions.
Global remittance isn't something people need very often, and there are already solutions for it.
BitCoin is not a very great store of wealth. Keeping a box of cash under your bed is more likely to retain its value than BitCoin. Storing wealth isn't even a very good idea, though, and if a person has enough money laying around they'd be better off investing it anyway.
Finally, being "resistant to government and bank controls" isn't very convincing either, and I would hypothesize advertising it that way actually hurts take up by making it sound subversive. A drug kingpin would love a money system resistant to the government and the banking system, but what actual benefit does a normal person get from it? And is it even a true statement?
