You're off on this... Aluminum is largely unsuitable for spaceship construction due to its temperature sensitivity and the fact that it makes anything constructed of it unsuitable for thermal cycling. Aluminum, unlike stainless, becomes extremely brittle when it's thermally cycled. It's an almost 5-fold temperature difference (150C to 1500C). That's not a small difference.
It also has additional cost savings over any other forefront material (eg. CF or Ti5) - like 30x for similar capabilities. If cost was no object, inconel would be the clear winner in most regards, but since cost is a significant factor.. We've known (NASA has) since the 50s that SS would be the superior metal used for such things, and here we are.
There is, arguably, nobody else in the space/rocket industry doing what SpaceX is doing, so I'm not sure how you could even have that criticism.
