Buying with cash is more anonymous than purchasing with BTC?

Of course. I'm always surprised when I read that some people want to use BTC to buy a soda. I always use cash for all my shopping. Also I don't want to pollute the blockchain with small transactions.

I can see the allure for using bitcoin to buy a soda, and hopefully if we raise the block size limit you won't have to worry about polluting the blockchain.

Well that's the whole point of btc idea - to replace fiat with it, regardless of the amount. If bitcoin becomes something that is used only on bigger transactions, then it has lost it's purpuse imho.
btw you're not polluting blockchain with small transactions, every transaction is welcome, as long as it isn't used to intentionally spam it with 0 fee transactions.

Your small transactions actually contribute in a positive way believe it or not!

I absolutely have no way to trace where the 20$ in my wallet came from.
However, I can trace a satoshi all the way back to its generation.

1. There is a serial number on it, so i guess it's possible
2. You can trace that satoshi, but you can't prove ownership at each address in that timeframe, meaning that you cant prove anything really.

How can you tell from serial number who gave you that $ Serial numbers served the different purpose you cant trace the owner from it

Exactly. With bitcoins, you can tell which address (or wallet) the satoshi was in throughout its life, but with a serial number... I believe you can only find out when it was created.

I don't think the reason for Bitcoin is to replace fiat. I think it's more about having freedom in the currency world.
But you're right, if not all the transactions are welcomed, it impairs that freedom.
