1) I hate paypal.
2) I would respectfully argue that your point about banks being safe due to regulation is quite false. On the contrary I would say that it is (over-)regulation that causes banks to lose sight of their reason for existence (hint: its not selling mortgages to fanny and freedie), protection of capital (a service they used to charge for - Remember monthly checking fees?).
Banks used to be in the business of protecting capital before the FDIC insured deposits for them at an insanely low price (relative to the risk the banks can take), thus killing the "Capital Preservation" specialized bank and entered free checking / free saving / free homes. Low reserve ratios and a never evolving asset classification (Mortgage backed securities were satisfying the reserve ratio for banks? Only government regulators could think up that one) allowed banks to play with everyone's money. Was it because of greed? Kinda. Exacerbated by having customers deposits insured? Now we're getting somewhere.
Your point is not necessarily wrong, since most regulation is just a standardization of norms and practices common in the industry. But regulation can be bad (as almost anything in excess can be). The real reason Paypal sucks is my next point.
3) The real reasoning for their horror stories lies in the fact that they are simply an intermediary (of sorts, I believe that Paypal, the intermediary, is separate from Paypal, the bank). Person X pays Paypal and Paypal pays person Y. There are many ways this system could break down, but the most expensive for paypal are:
- Person Y (the getting-paid) has their account hacked and starts scamming people on eBay, listing a lot of auctions and getting paid, never shipping stuff, and running with the money. eBay has made it harder to do this though, since you have to provide proof of shipping to get the funds released.
- Person X (The payer) - has their account hacked (or their just a terrible person) and they charge up $1,000 in online shopping. Person Y ships the merchandise and Person X files a chargeback against Paypal. Paypal must then freeze that amount, sometimes taking it out of your bank account, to make sure they have the cash in case they lose the chargeback claim (which is really easy to do).
In the end, I'm not really sure where they system breaks down. Paypal is over-zealous about trying to prevent fraud, but, unfortunately, they are at the mercy of the Credit Card processors. Its kind of amazing that they were able to create a market where they are bullied on all sides, by essentially bullying their customers.
