I should have written it as an option, not a solution. WFH will permit many people who dont like where they live, but have to be there for their job, to move away. This will reduce real estate costs and will permit people to buy larger homes near the cities they want to be in. Perhaps large enough to have their own home offices that they can then use to WFH if they choose.

WFH is win win I unless your income depends on being a landlord/real estate investor.
