You can choose the counterparty risk you are comfortable with when buying metal. Bitcoins you cannot.
Sure you can - you can deal with bitcoins in person (I've done this), trade items for bitcoins in person (have sold silver in person and been paid bitcoin on the spot), trade items for bitcoins via post (I've sold silver on this forum for bitcoin), or buy on a third party exchange. You can also choose to store them on paper, on a local wallet, or on an exchange wallet. Choose the level of risk you're happy with to acquire them, the level of risk you're happy with to store them. My "core" stack of BTC is now on paper wallets across two different SDBs.

And the vital flaw of bitcoin - the block chain file.
Already over 8 gig and people are not even using their bitcoins as frequently as cash. Once the velocity of bitcoin spending picks up there will be a problem. There will be another layer of counterparts as the whole system will need restructuring as the public won't have the computing capacity to download the file.
Never touched the blockchain or downloaded it, it's not required. I have paper wallets, android wallet and exchange wallets - I don't need the blockchain downloaded.
