Seems like your whole analysis is based on a fixed price for X bytes of storage, and is wrong.
Why do you say this.
The protocol/Network adjusts the PUT costs and GET rewards according to activity on the network.
As has been said before if # PUTs drop so does the farming rewards.
If Farmers leave then Farming reward rises
and a number of other conditions affect the price & rewards
Look up @dirvine posts concerning the cost of PUTs per unit going down as storage space increases.
The working of the SAFE network already adjusts so that this should not happen if the network/protocol is working correctly.
The only time 2 would occur is if there is nowhere to store the data, but as david says the farming rate will increase until enough people start farming again.
[EDIT: example where David talks of price being variable at any specific time and the dynamics worked out by the system The Safe Network's economics - #15 by dirvine ]
