More to the point: could you have build those same projects in the 70's/90's when those were new vehicles? I rather doubt it, too. Parts markets are real, but they take time to mature.

I mean... where do you think the parts would even come from? Tesla's factories are at capacity building new vehicles (in the case of the model S and X, they're actually almost a year behind orders!). Who's going to make the stuff you'd expect to buy anyway?

I do not expect to be able to buy replacement parts for a car that isn't yet on sale...

I do expect that I will be able to buy replacement parts for it once the car is on sale, as is the case with all of BMW's other vehicles.
