I think you are thinking about this too much. I know you would like to earn these big packages in Ohio. But honestly, what is more likely to happen is that companies will optimize for themselves too and if they are able to find good talent at cheaper prices (since cost of living expenses for employees are down significantly), they will do that. So on average SV salaries will go down as employees spread over US.

Can't have it both ways. SV pays top $$ because of 1) top notch skills and 2) cost of living. Now you are taking #2 away - so things will ease a bit
