You could probably get a 'MoneyPak' for $5 and say "there's 1k in this thing!!" Why not just hand over cash?

Ok lets clear this up,
Moneypaks will be sent with receipt if you ask. You cant purchase a $5 moneypak has to be $20 or more. You have to load it to use it.
Yes but I still see 0 advantage of moneypak vs real money
Well people use them for various reason...To load there debit cards,paypal,horse betting alot of ways to use it and has a good advantage.
