The possibility of bypassing capital controls is, for me, one of the best and highest uses of Bitcoin.
The fact that you can take a large value easily out in a Ledger or Trezor (or even with NO hardware <--- large balances in web wallets not recommended though) gives some protection of keeping some of your wealth under your control. And our friends at TSA would even have a hard time controlling taking a Ledger with you (whereas they could always STEAL your gold coins...).
Bitcoin represents some financial freedom. Bitcoin is a great diversification into safety. Diversification is a wonderful thing.
+1 It struck me the other day that one can use BTC now to completely do an end run around the rather tyrannical controls the U.S. government uses to keep its citizens from leaving for greener pastures. Currently you suffer heavy tax consequences if you try to leave the U.S. and renounce your citizenship, but if you convert your assets to BTC first, then in principle you can make a clean escape. That could be very valuable intel someday...
And loose lips sink ships… As exciting as bitcoin is, if you own more than 1-10 you best STFU!
