You're absolutely correct!
It's very difficult to beat 'free,' and cash transactions often are free - especially when transacting on a person to person basis.
However, historically, fiat currency has been a terrible long-term investment. No matter which is the fiat currency in question, they all tend to lose value over the long haul.
But, you still have a very valid and interesting point.
On the person to person level, cash transactions are free of charge.... and, as of today, this cannot be said for many of the other assets that are available.
But, as for being an adequate storage facility of value - cash really doesn't perform well at all. Then again, Bitcoin is also a little wishy washy in this area...
As always though, there are instances where Bitcoin triumphs over cash... and instances where cash is actually more useful than Bitcoin. I don't think that it has to be one or the other..
I have always looked at bitcoin as more of a system for the transmission of value - in this case fiat currency.
From this viewpoint, bitcoin actually compliments cash, and allows you to leverage it's blockchain to perform what are effectively cash transactions.
So, one way that bitcoin triumphs over cash is it's ability to allow you to conduct a cash transaction with someone who is based on the other side of the globe.
Looking at cash we can point out the obvious geographical and geopolitical limitations that exist - whereas, Bitcoin seems to be 'almost' impervious to these issues.
Cash has it's limits... and, where cash fails - Bitcoin prevails.
