Ok half of you guys dont quite fully get it. 

You can send coins from 19yScEhNciCzRsMF1ZECC4Y584rN9Z1dgo to 19yScEhNciCzRsMF1ZECC4Y584rN9Z1dgo.
That is, for some reason, a valid transaction.

I dont mean sending from one address to a different address that you also control, but using the same address.

The transaction fees do eventually kick in, but its a little silly anyway.
