A fanless CPU needs more, lower-clocked cores to have the same multi-thread performance as an actively cooled CPU with fewer cores, and higher core count CPUs cost more. So you only get a fanless CPU if you either a) get a low multi-thread performance CPU or b) pay for a high-performance CPU and then get only medium performance out of it by running it fanless. Notice that even Apple's highest performance laptops have fans; fanless there isn't a thing.
But Apple's fanless machines do b) and then they just charge you the premium. There are a few fanless PC laptops that do the same thing, but most people don't want that, because they'd rather save a significant amount of money by getting the same performance out of a less expensive CPU with a fan.
This is oversimplified. It is sustained multithreaded performance that brings throttling with fanless cpu. Anything for a short enough amount of time is fine, and sustained single threaded stuff is also fine. Bursts are also fine. A lot of work that people do on a computer is fine. Fanless doesn't really hurt unless you process large amounts of data in parallel for some time. Performance in a cpu does not only show in this kind of tasks.
I have used both airs and the max versions of macbooks, and the airs are embarrassingly on par for too many things. I understand it may be hard to believe, but one can do actual, serious work on a macbook air.
Of course one could say that ~having~ using the fan is always optional anyway (like the older 13" macbook pro was mostly an air with a fan) and in these types of tasks you may barely hear it. But still I prefer the peace of not ever hearing a fan for my to-go laptop.

5W Phone CPUs of today are faster than 105W workstation CPUs of ten or fifteen years ago. It's not a matter of whether it can do real work, of course it can. The question is, in the instances when you still have to wait for the machine, would you rather wait noticeably longer or pay significantly more money in order to avoid white noise? That's the trade off, and most people pick saving time and money over silence, so that's what most vendors offer.
It's not that they can't figure out how to do it. They do make them. There are AMD chips with TDP configurable down to ~15W and fanless laptops that have them. They're just not as popular when you give people the choice.

Can confirm. I used an Air for a couple of years as a bit of an experiment at work. Ultimately we did go back to Pros, specifically discounted M3 Max ones, just because I did start hitting bottlenecks running Xcode + Android Studio + Firefox + Slack + Telegram + god knows what else, I did FINALLY find the thermal throttling at the end and we ended up going with more expensive machines. That was over a year ago and I purchased the Air I had been using for my wife, who is using it today. It meets and exceeds all her needs and she loves the thing.
Ultimately I did have to cave and get a bigger Mac for work, but that was more out of convenience than necessity. I could've made the Air work if I wanted to, but ultimately I wanted a larger screen and more displays.
