I agree with some of the points, but not necessarily with the conclusion.
Yes, some employees value remote work, but not all and not always the best ones. In a lot of cases the remote work was an economic decision - get FAANG pay, work from a cheap location. No commute is definitely a big plus and considerably improves quality of life.
But there is also a downside to remote work - less learning, less creativity, less bonding and networking. It may not immediately become apparent, but over several years it does accumulate.
It is unclear what "the best" employees value - some may value remote work, but very likely they value more a creative and stimulating environment, where they brainstorm challenging problems with smart colleagues, and generally be surrounded by like-minded people.
People young in their career don't do every well remotely. But they also won't do very well in the office if all of the experienced people are remote. And nobody wants to waste time going to an office only to do Zoom meetings with remote people.
So we'll be back to on in-office or fully remote setup.
Unless of course it's a single-person or non-creative type of work, which is an entirely different organizational thing (an accountant can work the books from enywhere, for example).
