>Would you say that accessing coordinate 0,0 is a "logically invalid operation"?
If you have a matrix that starts at cell 1,1 then trying to access 0,0 is absolutely a logically invalid operation. I'm not saying that 0-indexing is illogical, I'm saying that dereferencing null/nil is illogical.
As for the rest of your post, the scenario eridius came up with is pretty weird, at this point I'm just going to shrug and give up on analysis.
