It shouldn't be impossible for Apple to offer models with and without. Let the market actually decide. Something tells me that if Apple produced exactly the same model of MBP, one with and one without, you'd see a huge preference away from the Touchbar. I could be wrong! But it would be good if users had the choice.
Apple isn't in the business of giving user's choice. I think their argument always has been against the inertia of familiarity and in the case of the butterfly switches and touchbar it's bitten them in the ass but they can't undo the choice for whatever reason
