This sort of thing is not optional anymore and just dicking around with an unmanaged laptop and copying stuff onto unmanaged drives will be more and more difficult.
This stuff is not because of distrust or to make your life difficult. It's to protect the company and its customers.
What they should do though is support all business required OSes, not just Windows. Our company is pretty good at that and despite me doing all the work on managing non-windows compared to entire teams of Windows management people it works pretty well and users are happy :) Though I recently moved.
Not always about the amount of security software they have to deal with but these are just needed in this day and age.
I do understand your frustration though, as most enterprises don't care about developers if they're only a single-digit percentage of users, and have terrible IT processes like ITIL.
