On Linux you could automate that task. How would you propose automating "open disk utility and click a few buttons" on Windows?
This is less of a "Linux can't" issue and more of a "I quickly know how to do it on Windows after years of experience and I don't know how to do it on Linux." Linux not being identical to Windows isn't a flaw. No one blames you for not wanting to relearn, but pretending like Linux is bad because your Windows muscle memory doesn't apply is nonsense.
