Touchscreens can serve a function. And that’s predominantly when you have your laptop atop your lap. In a cafe or on a plane where even operating your touchpad may be hard for a lack of space (or for me size of gut). On the couch is another scenario like that. If you don’t encounter those situations a lot, don’t get it, especially if it’s more expensive. If you hate fingerprints on any screen, don’t get it. If you’re not sure and money isn’t an issue, take the extra feature.

Your post is in danger of being deleted because there isn’t an open-ended question in there.
You maybe had better address this question to developers or in communities dealing with building out the fediverse in particular.
