Just because they are not able to work from home does not mean that technology has not affected their work. More importantly for the purposes of this article, technology may still affect the importance of proximity in land uses. A call center worker may not be able to work at home. But thanks to cheap communications the job can be moved overseas, thus reducing the value of land in rich countries. A health care worker may not be able to work at home. But if someone overseas can read the x-rays, there's less need for land in the rich country. Moreover you say you know only three who can work from home full time. Others may be able to work from home part time, which gives them freedom to live farther from work and commute. These are obvious arguments in an age of blanket 4G coverage but this piece doesn't even address them.
