Ok so my counterargument :)

1. So is Bitcoin, spread the words in separate locations or just remember a few of the words. And i did not mean stealing part of it but rather moving it, taking it with you. Try take 10kg gold through customs. Beside the weight they will for sure stop you for many reasons.
2. Not sure what you mean, gold on blockchain? Either way with so many corrupt governments, banks, politicians they can do what ever is best for them. With Bitcoin they can not physically confiscate it, nor can they stop the internet completely.
3. agree
4. Does not matter, the point is to move away from using a thirdparty no matter how good they are. And having privacy is the right of every citizen. No one should know how much money i have or what i use it for. It is exactly this sort of mind game government play to scare people and let the banks get more power of our money. And in this day and age gold doesnt really have any appeal to young people. Maybe governments but not people. Crypto on the other hand will grow more rapidly with better wallets and dapps.
5. I actually dont like the LN, there are far better option like PIVX, DASH and hopefully ETH once they upgrade. And again i dont like thirdparty involvement.
6. I'm not in the US so not sure how that applies here. I actually dont think tax is a bad thing. BUT we pay way way to much and there is no way knowing where the money is going and what its used for. With blockchain that can be tracked. Anonymity is for people not governments.

I do hope we can get rid of all money but to be realistic i dont think we will ever get there totally but yes i agree that we will have a much better accountability and transparency thanks to Bitcoin. It might not even be Bitcoin that will be THE coin but something will come out of all this sooner or later.
