$\begingroup$ I understand where you are coming from. But to me, even if an array is the only possible way to get constant lookup, I can't really say definitively that we wouldn't be able to lower the removal and insertion down to logarithmic time with some trickery (some pretty clever data structures can be implemented in an array alone like an array based heap for example which has many logarithmic operations). This would be different if you could somehow prove that you couldn't. As for the model fitting, I can't really make assumptions about the data. Also isn't the insertion into an array linear time? $\endgroup$
