there wouldnt be a limit-you could be tradeing alot and need alot- to how much you could collect but yea have strategic resourses only last so long so you have to be doing something with it or you would lose it
The Resourses would still be there but if you didnt use what you had stockpiled after X number of turns it would be lost but this wouldnt matter if you still had control of the resourse
