The short answer is No
[wow it's been a long day].
I've found a few ways to combat that feeling, but the truth is that I just come to Quora less often as a result of the credits system. It's taken a bit of the whimsical joy out of the experience for me.
For one thing, you can negate the credit system in your direction by making it free to ask you to answer questions
. It's an obscure, frankly annoyingly buried setting that I can only seem to find when I search Quora for an answer to that specific question ("How can I change how much it costs to ask me a question").
Fortunately, for the most part, you can also decide how much you're willing to pay someone to answer a question. When the person is suggested to you, you just click on the number Quora suggests and you change it to the price you're willing to pay. This has very limited success, and it doesn't seem to work at all if you have to go search for the person in question (there's no dialog to change your offering price in the search results), but it's something.
With regard to the other questions, it is a bit of a shame that the system has turned answers into commodities with specific, finite values. Moreover, it downright sucks when an answerer goes "undervalued" for no particularly good reason. It's obviously demoralizing for him/her more than anyone else, and I'm sure it's discouraging to see that the sum total of all your time spent on Quora only amounts to a pittance of credits.
With that being said, I think there have been/will be "Quora credit freaks" for as long as the site is alive. If they don't obsess over their aggregate credit score, they'll obsess over the number of upvotes they get on particular answers. Is that any better than a credits system? Perhaps, since credits are being used to limit our interaction with other users, but then I suppose that was the point, wasn't it?
I can only imagine that as the site got bigger and the userbase grew, the team needed to come up with a way to mitigate referral spam within the site (keeping everyone from getting inundated with "Ask to answer" requests). The credits system was a hackneyed (but effective) means to deal with that issue. Hopefully the clever people at Quora will come up with a more inventive solution to the problems they initially solved with credits.
