I don't think so. Just last week I signed up for unblockus.com; $5/month. Every domain name registrar on the planet - $12 a year or so. Full automated services should not be subject to a monthly minimum, and they shouldn't need support.
> people who pay low amounts are the most demanding in terms of support
Do you really think this would be a big factor for Dropbox? If so - just say any under-100GB account has the same support as the free account.
> Is $10/month too much for you?
Well no it's not, obviously, since that's what I pay. But I am the only person I know with a pro account, since it's such overkill, and even I kind of resent paying for so much more than I need.
I like Dropbox, I want to use it. Just let me pay an appropriate amount for an appropriate usage!

I am guessing you are pretty young. You will be amazed at how quickly your tolerance for such things decreases with age. Free space for completing tasks? That does not even make sense, because if you have to complete some task it is obviously not free. How about I just do my job, and buy things I need (like dropbox), and everyone is happy.
If dropbox worked on a usage-based billing model they'd never net nearly as much income as they do offering ~100 gigs to users who would barely use ~10 gigabytes of space a piece on average.
I wonder if Dropbox might make more money if they charged $10/month for 20 GB, because 20 GB is not more than most people need. (It would be a worse deal, but if the main problem is having more storage space than you need...)

That is the point. As the value of your time goes up, so should your willingness to pay $10/month. This is price discrimination, with price points of $0 and $10.
I agree with the general point, though: coming up with something to accommodate a $23 yearly budget for 14 GB is not a good use of their time relative to, say, finding the next million people who don't think $100 is a lot relative to "all the data my life depends on."
Well right now they're charging $0 which is even less of a business for the same amount of hassle. I'm in a similar boat, I would like more than 2GB but am not interested in 100GB. Regardless of the money, it's the psychological thing of paying for something that I know I won't use.
No, I don't think that's the biggest danger for Dropbox.
For pure backup there's Backblaze, which is much cheaper than S3
Ignore for a moment that 100 GB is more than you need. Is $10/month too much for you? Well...

And then there's of course the competition.
