First off I'd like to make it perfectly clear that I oppose account sales.  I would venture to guess that the vast majority of times accounts are sold or bought for deceptive purposes.  Even if no scam is intended, the buyer might only want to elevate his rank to earn more in signature campaigns, which some may argue is a mild, or even acceptable deception, it's a deception none the less and I'm opposed to it.

But I'd like to paint a hypothetical scenario where I might actually find the sale of an account as acceptable:

Lets say for example a member has an anonymous account used solely to conduct a service that doesn't require clients to trust the account.  The owner of the account and service decides he no longer has the time or desire to continue operations.  If one were to have such a service that's profitable, valued by it's clientele, and would be sorely missed if it ceased, would it be acceptable to the community if the service along with the account were sold?  If the account and service were offered for sale out in the open, transparent, and continued to operate in a way that didn't require it's client's trust, I think I would be okay with such a scenario.

Obviously, this would be a very unique case and I'm merely trying to open up the discussion (play devil's advocate.)

Theymos has refused to ban the activity, probably in part due to his Anarcho-Capitalist tendencies (I speculate.)  Since I tend to lean right-of-center I understand this, and back his decision.  It's his decision to make, after all.  

So, I present this question to the community:  Is there any scenario you could think of where you would find account sales acceptable?
