Make sure it is not in discovery mode. This is what causes it to automatically turn on by itself. Also if you have other bluetooth devices in discovery mode, they may force a nearby Bluetooth device to turn itself on. Turn off discovery mode in all devices until you are ready to use Bluetooth.

Thank you, but it wasn't in discovery mode.
I have turned off *my* devices, but I won't be able to control any others
In any case, I don't quite understand why the mac's own bluetooth sub-system should turn on, if there's another device that's seeking.

I think what may be happening is other Bluetooth devices are within range outside. Remember it is wireless. But another thing this could indicate is something is inducing the wireless to turn on by itself. Nearby magnetic fields, microwaves, car radars, etc... How far are you from your nearest neighbor or the road?

There'll always be a bluetooth device around. The mac shouldn't turn on bluetooth just because it saw a device
I unchecked "Open Bluetooth Setup Assistant at startup if no keyboard is detected" and a similar one for mouse. Let's see if that helps.

Turns out that many who have iPhones have difficulty with it turning on their Mac. If you have one, check the iPhone forums to find out what people have done to stop that from happening.
