If you fly an ODP, you will have terrain separation. It doesn't matter

Nor would there be an ODP to fly!

True enough. But, Murphey's Law being what it is, some might conclude that the lack
of an ODP at a VFR airport means diverse departures are approved.

Well, then, they wouldn't be able to fly an ODP if there wasn't one there.


I think you're missing my point. There are many IFR airports that have Part 97 IFR
takeoff minimums but no ODP because they are 40:1-clear in all directions once reaching
400 feet. That is the result of a survey by the feds. There aren't any such surveys or
takeoff minimums at VFR airports but some Part 91 pilots don't understand the distinction
since takeoff minimums are mandatory for them.
