Untrue to say they don’t last, our M1 macs 6 years later are still very usable. However your point is very true for corporates, staff always want a refresh regardless if the laptop is good enough or not.
These personal plans make sense for people who want the latest and don’t like the hassle of reselling

My personal experience disagrees. A lot of colleagues are absolutely happy with keeping their machines for quite some time. A lot of it - believe it or not - is simply inertia. Apple has made switching MacBooks super easy but still the process of going through the migration process from one machine to the next simply isn't worth the trouble for a lot of them (and I include myself in that group as well).
If all your people are looking for is the latest and greatest gadget then you may simply have the wrong people in your team.
