For me, it was a choice that I have never regretted (except for not going to the prom). It put me on a career track where I was years ahead of my peers.
For my kids, not so much. They had such bad experiences in high school that they are sour on higher education. I am still working on convincing them to finish a college degree, but I feel like a hypocrite because I did not get mine until age 50. Back when I was their age, I was lucky to work in jobs were nobody cared whether or not I had a degree. Today it's impossible to get a "professional" job without a degree.
The CHSPE was a godsend to me. I fit right in at Jr. College and got along well with my teachers and classmates. The environment was different because my peers were (mostly) emotionally mature, and they wanted to be there. High school was like a prison in comparison.
I was also fortunate to find a career path that didn’t require a degree, and while my oldest child had no choice based on her career interests, I’m having the same struggle with my youngest who’s in her freshman year with an undecided major.
Then came university and that all went away, seemingly forever.

So, sure, you can get hired as a web developer, or even some non-web development roles, but that's kinda pointless because if you could stand doing boring shit you'd finish the academia to at least a very basic level.
TL;DR: If you couldn't stand the uniformity of school, then the roles available to you without a formal education are going to be just as boring and unrewarding to you anyway.
The last half of my career was spent doing cutting-edge research and development with some of the best and brightest people I have ever known -- about half of them with at least one PHD.
Sometimes ability can make up for lack of credentials, but it is rare.
That is why I hedged my assertion with "likely" :-)
Outliers always exist.
The ones who did (https://en.wikipedia.org/wiki/Aorta) biology might remember it :-)
I don’t think trigonometry or foreign language is an essential skill for 99% of people. But explaining simple ideas in writing, or being able to compare the costs of a yearly vs monthly billing plan, or knowing how birth control works are pretty important life skills.

My take:
You don't learn to remember what you learn. You learn to build roads, pretty much literally inside your brain (it constantly rewires).
It's more like unpaved paths before road building: First there is wilderness, then there is a lot of traffic, and increasingly that traffic concentrates on more and more clear paths.
The learning of "stuff" is creating paths. The things - ideas, knowledge, facts - that you learn are like the carts travelling the paths. They may be gone - but the paths remain.
So even after every single thing is forgotten - every single traveler and cart is no longer there - what remains is the paths. The wiring inside your brain changes in the learning process. You may not remember much of what traveled through your brain, what created the paths, but your brain nevertheless remains changed.
Even if you forget every single thing, the way you think and react will have changed forever.

Using the metric "what I remember from my courses" is the wrong metric. Instead, it should be "how did my way of thinking change".
I took a lot (really a lot) of (mostly university level) courses long after university, in fields unrelated to my career and previous study. That's when I noticed far more clearly than ever before, despite very good success (I was even made TA a few times), the concrete things I was able to recall even just a year later was really small. Then I noticed it's the same with my core field really.
The concrete things we know is actually rather small. I forgot sooooo much. Only things I use regularly are available in a way that I could pass an exam (school or university). Still, I changed quite a bit, but it's all "meta". I now know the path I have to take instead of being lost. Even if I don't understand the concrete items e.g. in a medical paper (e.g. names of some genes or proteins), instead of feeling lost I have a "feeling" what it is about, and I can easily look it up and understand very quickly because I have a framework ready to receive what I read.
Our actual "memory" is pretty small, it's all about the paths. Literally, in the brain.
I think it is both. It also discourages to think. I had to re-learn most of the things becasue I was told BS in the school. The current school system is outdated because it was designed too long ago.
But I'm going to guess the overwhelming majority of people who think it isn't for them actually need it quite a bit.
I also think for self motivated intellectual kids, completing high school anyways really isn't much of a roadblock or time waster.
