It's a big issue to build tools for others to use - an excel file on a shared drive somewhere might be developed by one person with python installed and elevated permissions but used by 50 with no python installation etc.
IT arn't going to adjust their policies for a small group unless they have significant organizational sway.
It also does not require admin permissions in Linux, although most distros do not offer a happy path for that.
Not really sure how this is a rebuttal, maybe what you say is true on a default windows installation, not on an IT-dept managed system.
I'm sharing my experience of this exact problem we have right now. Users cannot install python on their machines, in an org of 60k engineers, asking for changes to a small group of users comes with heavy resistance from IT.
On these machines (most computers in most offices in every western organization) no software can be installed from online, and running any form of executable requires IT/Admin elevation.
It's like you guys have never worked in an office in the real world that isn't dev/tech.
That said, VBA is slow.
