I think it’s about being able to out the rocket back together, making repairs, and not having to move it for its launch. Sure they could land it somewhere else, but then how much does it cost to get back to the tower? Also it’s just massive and tall. The more weight and height, the wider and st...

I would also assume build arms or something to fold down to protect the engines from being crushed would add more weight. Making the booster as light as possible means lifting more cargo. It has to reach 17,500 mph to enter orbit. So the Chopsticks make sense.

Off the top of my head 1) No landing legs so they save the weight that can be used to improve the performance of the rocket 2) No landing legs also means they can save time between refurbishment since they don’t have to go through the whole folding the legs back into position. 3) Landing direc...
