The way it works is similar to attitudes toward remote work (until a few months ago): barriers help people waste time and get away with stuff.
Control is not all about what an authority can do (which is actually the least efficient form of control), it's also about what other people are prevented from doing, sometimes structurally so, as in the context of office layout and design.
Sure, there must be times when ~everyone is available to talk. But otherwise, just let people work when they're ready to work. And let them self report their work time.
That's why "Busyness" and "Butts in Seat Per Hour" are seen as proxy for productivity. That's also why politics play such a big role.
Until we find a GOOD way to measure productivity, Control and "Busyness" (the illusion of productivity) is unfortunately not going to go away.
I thought to myself: "what if that was the etymology of the word, how ironic".

Oh wow.
This conflicts with the much, much stronger profit motive.
Employers can still calculate "profit per worker hour". And it's arguably more accurate when based on reported work time, rather than just days worked.
It is not. It's specifically used because of the utility in the simplest tasks. Factories are designed around throughput and efficiency of workers.
You say that salaried people aren't paid by the hour, but that's arguably a fiction. There's always a defined work day. Some employees end up "working" for inordinate amounts of time. And some employers do push employees to be more productive.
So if the standard is 40 hours per week, I'm just saying that you do the work whenever, not eight continuous hours per day, for five days per week. That decreases control of employees by employers.
Even if the floor space itself is open, that doesn't mean that decently high cubicles (or even floor to ceiling dividers) had to go along with it. How much is it really saving to shave 1-2 feet off cubicles for your six-figure staff? Smart workplaces don't think twice about $400 for a second monitor.
Say occupancy costs (all in) are $60 psf. Now assume occupancy is around 1 employee per 200 sf (inclusive of indirect circulation space). That means occupancy cost per employee is $60 x 200 = $12,000. Now make some assumptions about the total labour cost (salary, bonus, benefits, etc) - say $200k - and look at how little the occupancy costs are relative to that - 6% with these examples.
Jam more people in so you get it down to 1 employee per 150 sf, and you've saved $3,000 per employee, or 1.5% occupancy to labour, which can easily be lost in terms of decreased productivity with people shoulder to shoulder.
Lesson: You need only a very, very small change in productivity to counter any savings in relation to occupancy. And not just in terms of productivity of existing employees, but also the cost of lost productivity due to lower retention, or lost productivity due to more sick days given the closer proximity. This is why I've never understood why companies go anywhere but the best locations with the nicest office space... People really are the major cost and the only asset a company has. Do everything you can to make them love every second at work. The added cost of free food, nicer office, better location, etc is insignificant.
The Open Floorplan operates a lot like that.
But they also lower cube walls, or make them transparent, which goes completely against this theory.
Open offices are crazy cheaper, and most retail developers don't build real offices anymore (and or when they renovate a commercial property pull all these walls out).
It is about cost, for anywhere I've worked or any clients I worked for. I haven't ever known a manager that wanted an open office to control or oppress their staff.
This is (mostly) why new occupancy tech exists as well btw -- the "crotch sensors". Not usually for specific employee surveillance, but to map occupancy trends and determine what parts of a space can be hot-desked or otherwise over-assigned to further reduce space requirements.
