ELI5: Why does online credit card fraud still work? Aren't those who use a stolen card # identified / prosecuted once they send something to their address?

Long time lurker and also a fraud investigator.

A lot of times hackers will steal a large number of credit card numbers and sell them in lots of hundreds or thousands. The buyer of the credit card numbers will typically set up some type of account where they will charge all of the cards for small amounts, say 10 or 50 cents, and make it a recurring charge. Many people won't notice these small charges, so they will continue to be charged weekly. 

1000 cards weekly at 50 cents is $500 a week. 

They will then launder the funds by using them to purchase bitcoins, or moving money off shore. 

The amount of time to investigate this type of crime and try to bring the case to prosecution is typically weeks or months. For that small amount of money most companies will just cancel the card numbers and chalk it up to a loss.
