I don't know if you've worked for an "established" corporation developing software before but most of what they pay you for is dealing with internal (arguably mostly social) stuff. Some minority is actual useful software development work.
Not really. They pay you to deliver something, but you also need to coordinate and interact with people. That involves coordinating and syncing.
There is absolutely no position or role whatsoever, either in a big corporation or small freelancer gig, that you do not need to coordinate and interact with people.
Pray tell, how do you expect to be paid while neither delivering results nor coordinating with anyone else?
