Ignoring the other side of the story is what's going on here.

1) because I like cash, I like the feel of it, it's real money not bits.
2) Because I don't trust my banks.
3) because they charge fees to transfer the money same day I don't want to pay
4) because I don't like the government and I don't want them to have records of my business transactions if I can help it. I'm honest, I pay my tax but I don't want the IRS keeping records on where I buy my car and from who.
5) because I get a discount for paying in cash.
6) because I borrowed the money from family who do business in cash.
7) because I'm paying someone who prefers cash.
8) because I have to pay 30 different people and I don't have all their bank details.
9) because we've always done payroll in cash.
10) Because I'm taking the cash overseas to a country where US Dollars work and electronic bits don't.
There's 10. There are at least 100 more. And loads I haven't even thought of.
Using cash is a right, and you should feel bad.
Clearly you like breaking laws given your posts and should be arrested and have your property confiscated. What other reason could you have for your lack of respect for law? See how that goes? In soviet Russia, you're welcome.
A legitimate reason would be whatever reason I happen to choose, no different than if I choose to use a credit card, Bitcoin, or write a cheque. No one should have to defend their legal transactions to you or anyone.
That said, some governments are moving down the path of outlawing large cash transactions. Here is one example: http://www.forbes.com/sites/jonmatonis/2012/10/17/large-cash...
You may be doing payroll for a small business that pays cash. You may have collected cash from a door-to-door sales job. Possibly you've withdrawn cash to put down as a deposit on an apartment or house. Maybe you're paying for a course for professional qualifications. Maybe you owe three month's back rent.
I'd reckon that all of these put together are more probable than funding a terrorist cell or setting up a drug deal. I'd certainly not give up my rights to do these things "just in case".
Second, there are, for example, antique fairs where sellers are not going to take a check from random unknown buyers rom all over the country. Also, some people, notably some immigrants, of which there are a historically large number now, do not trust banks or bank instruments, or simply do not know which bank instruments would be trusted for which types of deals.
Or, are you really asking, what is the RATIO between what you'd deem "legitimate" reasons to carry money and what you'd deem "ill-legitimate"? What is the correct ratio? If we take 50% of the "bad guys" money, and 50% of innocent citizens is that too high? 60/40? 80/20? What is the correct ratio? How can you even know?
