No no, the problem isn't reaching across the desktop. The problem is literally taking your fingers off of home row. It's fine if you're in a phase of your activity where you're moving slowly, contemplatively. But if there's a series of tasks that we want to accomplish and we already know what they are, lifting your fingers off of home row will slow us down! Wireless vs wired mice have nothing to do with this.
As far as what is considered to be hard, it depends on the individual.
For many of us that spend a great deal of time on the command line, many multi-step activities, including those related to file manipulation, become like a single action. Consider the difference between touch typing and hunting and pecking. To an experienced secretary, the phrase "to whom it may concern" can become a single action, executed by the fingers without any thought whatsoever, while for an inexperienced typist that's 20 individual actions. Similarly, a whole series of file manipulations, git actions, SSH actions, become hardwired into our muscle memory and we don't even think about the steps. We just decide that we're going to do something, and let our fingers take care of it. This is much easier and faster then manipulating a GUI with a mouse.
I can observe the sun is hot, but doesn't mean I can tell what temperature it is. I think without data of timings across different applications and uses, it's hard to prove either side. I am open to both sides having the possibility of being quicker
