Smudges are off-putting... but, there are times when it would be very convenient to be able to scroll or click on a touchscreen. There are times when presenting when a touchscreen would be preferred over a mouse or touchpad. It's not often, but they are nice to have.

And, in regards to smudges, I mean, just don't use the touchscreen unless you have to and problem avoided.

Antiglare can be a thing but that can be avoided by avoiding string lighting behind you.

There's still the issue of accidentally triggering things (when e.g. adjusting the screen) and sometimes you don't have control of your surrounding lighting. I'd still prefer touch to be entirely optional.
