I constantly see references relating to DDoS attacks about how IP spoofing is such an obvious trick to use but I've never seen any way to actually do it. Why wouldn't every device on the internet spoof their IP?

That's not to say that DDOS attacks stop being possible, but at least they become traceable.
Most countries don't allow cars on the road that are unsafe due to lack of maintenance. Perhaps it's time to do something similar for internet-enabled devices that cause serious harm to others. Hold the user, manufacturer, or network operator responsible for harm caused by their lack of maintenance.
to add to that, You'll defiantly get some mis configured servers with 1000Mbps uploads. And those will be really easy to pick out of the lineup. And then you'd probably be able to call the DC and say that they should block that IP at their boarder and they would probably also comply because there's a good chance that customer that was doing 110Mbps and won't want to pay for 1000.
As it is now, because the source is spoofed, you can't really take the source offline, only take the destination down to keep the other hosts in close proximity running.
With a TCP connection you can pick the source and drop the handshake, basically never start the connection. Some of the windowing can be used to make a tcp connection less of an issue as well.
