Because it sucks to accidentally activate a function by bumping your nose into the screen.
I agree 100%--

Allow these two characters to help you 2.
many times these "features" get turned on or off by mistake, I do not need nor want a touchscreen, in the old days and even today I would tape my camera up so nothing would move. I do not need a long list of features, that just get in the way, keep it simple think about the image one is creating not what extra "feature" is missing

So you don't need it... but is is useful for many. As said you can turn the feature off. If sony provides it automatically turned off then unless you dive into the menu system to turn it off you should not have a problem with it.
There is a saying... it is better to have a condom and not need it than not have one and need it. I find that tends to apply to a lot of features. For those who do movies casually (since this is also advertised as a video capable device), it is nice to be able to focus on one subject then to the next without having to learn how to manual focus (especially with most of these fly by wire lenses), or invest in additional gear to be able to do it.
Lastly, sony is pretty much the camera manufacturer that seems to through in all but the kitchen sink. It is just odd for them not to have a touch screen... even nikon got onto the bandwagon. Business-wise it also makes sense for sony to include it. It is far more annoying to miss shots from an AF point selection perception compared to the very rare times when you would have accidentally turn the feature on and bumped and slide your nose onto the screen. I imagine it would also be a trouble optional thing... touch screen off, and touch pad like operation, making the issue you mention even more unlikely.
