Not how the Internet works. Yes that's true on the edges but once you enter into the public Internet, packets could be routed from anywhere to anywhere. The only solution here is to shut down ISPs that are participants but you're talking about getting participation from people that often are themselves involved in the criminal enterprise (that's true for US, Europese, Chinese etc providers) and are profiting from these attacks through overage fees etc.
You wouldn't imagine but even providers like Verizon won't shut off mobile connections because they are often charging their customers per GB consumer. A lot of sleazy hosting provider (the cheap $5/mo.VPS) simply delays intentionally or unintentionally because they don't have the staff to keep up and they are often paid for by the criminals.
