(While it's clear you've done a ton of your own research for your own case.)
Steve Kerr's advice after his own back surgery complications (albeit microdiscectomy, not a laminectomy) make me hesitant:
"If you're listening out there, if you have a back problem, stay away from surgery... Rehab, rehab, rehab. Don't let anybody get in there."
I helped a friend through a microdiscectomy, and it could not have gone better. Laparoscopic procedure, short recovery, lifechanging reduction in symptoms. The biggest hurdle was that their insurance required PT/rehab prior to authorization, even though all the experts involved agreed that it would not help.
This kind of comment is only marginally better than "well, I asked ChatGPT and...."
You acknowledge the parent commenter knows more than you, but you decide it's somehow helpful to post contradictory information anyway sourced from someone else who also likely knows more than you.
The heuristic I found when researching this a few years ago was slightly more nuanced than your quote: back surgery is very likely the wrong solution for back pain.
But if you have nerve problems caused by an issue with your spine, you probably want to address them before they become worse or irreversible, and back surgery may end up being the only option.
