Git is _incredibly_ complex to understand, as proven for almost 20 years by the vast majority of people who have been forced to use it. And by quite a bit of academic and industry research, for instance, [1].
I can teach you Grace in about 15 minutes. How many days and weeks does it take most devs to start to understand Git? And even when they do, for most, it's only the basics, and please don't let anything go wrong. I mean, there were people for over a decade who made their living running week-long workshops on learning Git. I don't see how you could run a half-day-long workshop teaching Grace, unless you go really slowly.
If you're one of the probably 20% or so who really feels like they understand Git and are in control of it, that's awesome. But you're projecting your experience more widely if you think that's the norm. It's not.
As for local, well, if you're working with a team on GitHub or GitLab or Azure DevOps or some other hoster, you're already doing centralized VCS, you're just using a decentralized VCS to do it. Most shops don't let you push to production from your dev box, right?
