There is one version of this idea that I like though, which is that I doubt that we're built for 8+ hours a day of intense abstract reasoning, which seems to be what the modern information economy demands of those aspiring to a middle class or better existence. The vast bulk of humanity did not earn their daily bread this way for most of human history, so I don't think our brains are adapted for "abstract reasoning above all else."
As an aside, drug use was extremely common among indigenous peoples all across the world. I don't even think this naturalism fallacy supports these particular claims.
It's very useful to recognize when we aren't 'made' for something, because it implies we can get benefits from either avoiding it or supplementing our performance at the task. When we are "made for" a task, like walking for long periods or throwing objects with good aim, it's tough to improve on human baseline. (At least, not without serious side effects. There's a reason drugs to boost strength and physical endurance tend to be risky.)
But that distinction has to be kept separate from a values judgement. As I mentioned in another comment, "reading a good book" is something I'm not evolved to do. That might mean I should be prepared for challenges with the task (e.g. back pain if I sit for too long), but it's unrelated to whether I want to keep doing it.
The 'ancestral environment' stuff is likely to be easy or optimized-for, but that's not the same as being a better way to live.
There shouldn't be any easy way to improve on what evolution tried to do, because evolution would have done it. But there can certainly be ways to optimize for things evolution didn't try to do, like preparing us to do symbolic logic for 40 hours a week or stay up well past dark. And there can be ways to optimize for goals evolution didn't/couldn't reward, like "never having kids and staying healthy until age 90".
I do think there's risk in blurring the moral point with the practical one, though. I'm not particularly evolved for reading books, but it's something I enjoy and I want 'hacks' to do it better - whether that's reading glasses or a cup of coffee. I don't like commuting while tired or being stationary for hours on end, and if I had free choice I'd stop doing those things instead of hacking myself to be better at them.
But in "enhancement" terms, they both count as "doing a thing I wasn't made to do" regardless of whether I want to keep doing them.
