OK, either I received the money from the future or I didn't. If I did, then
how can I *not* decide to send it back now? If I didn't, how can I change
the past by deciding to send it back today? And if I could decide to send
money to myself in the past, wouldn't that create a feedback loop? E.g., I
send back $1000 that turns into $5000 today which I reinvest in the past so
it grows into $25000 today which I reinvest in the past...
