I’m discussing version control.
If the OP is referring to version control because they're needing to handle multiple branch types, switching between versions etc that is much more involved....but also makes it even harder to see how you can manage that by simply dropping version control entirely?
From the article, it does seem like it's not about any sort of specific feature they use, but rather the sheer basic "save versions of code" aspect of VC:
"Version control kept me attached to the past"
To go back to an earlier comment, this honestly sounds like burnout to me if you're having temporal anxiety from saving code.
