Whether that is the assumption or not is a matter of your personal level
of paranoia :)

If by "avg users", you mean "average people", I would suppose it isn't a
huge concern... but I don't know enough about Tor's "average user" to be
able to comment further. It seems like it would be a failure of the Tor
project if anyone could confidently assert what is an "average Tor
user", as it would imply that someone can tell that 1000 unique Tor
users visit wikipedia in a day, vs 5 who visit very frequently.
That being said -- I believe (and I could be wrong) that Tor's target
audience is really those living in repressive regimes and subject to
censorship, and of course the whistle blowers too. "Once is enough"
definitely applies to those people. The rest of "us" just get first
rate privacy, and our traffic helps obfuscate the traffic of the people
who *need* anonymity.

Probably not :) ... But don't underestimate the power of larger
businesses (financial, recording/movie industry, oil), and their ability
to get what they want from governments.

Fair enough. I just said that because of the solution you provided --
changing fingerprints midstream. It suggested that you thought each
relay could view your traffic directly, and that you didn't understand
that your traffic is wrapped in layers of encryption that are "peeled"
one-by-one as you reach each successive relay. Since these layers of
encryption are a fundamental piece of how Tor works (and why it's called
"The Onion Router"), failing to understand that would be a "gross
misunderstanding" in my book :) No offense intended, I assure you.
