You're missing the third possibility, which is that efficiently doing what PayPal requires requires "treating serious customers like dirt."
PayPal is in the business of efficiently detecting and not paying for fraud. One type of fraud that they need to deal with is fraudsters getting control of an established account, sticking lots of fake payments in, then withdrawing the "money" before PayPal notices that it isn't real. Their strategy for this seems to be to make people jump over a low paperwork barrier, then wait long enough that the payments have all cleared before they pay out. Given this, paying for a dedicated customer service representative for the victim on top of that strategy is an inefficiency.
The last part of that decision ignores the effect of pissing people off on their reputation, and so may be shortsighted. But the rest of their strategy makes sense to me.
