Why is it that transferring money from my bank account to my Paypal account takes "3-4 business days", but sending a payment to someone, where the source of that payment is my linked bank account (the same account, in fact) happens instantly?
Where is that 3-4 day delay coming from?
If the delay were in the other direction (from Paypal to my bank account), at least there would be the dubious justification of earning a few days interest on the money while it sits in limbo, but adding a delay to incoming money makes no sense at all.
