Re: One thing I will call out as BS
If companies who made better choices are able to poach the best staff from those who made worse choices then the latter are liable to go broke sooner or later and the inflexible landlords are going to lose their tenants anyway.
I suppose some property owners are going to let their tenants quit if they want to, repurpose* part of their buildings into something more sustainable such as mixed residential/business**. Those who aren't are going to find their more flexible competitors got there before them so they're picking up the crumbs.
* Yes, an upfront cost but needed to retain some value in the property.
** This may be an issue with planners. OTOH the planners have actually planned an unsustainable commute-based economy. By definition if it's unsustainable it can't be sustained and will collapse. Those authorities which catch on quicker will make the necessary adjustments. Those who don't will find themselves running the sort of derelict areas found in ex-industrial areas.
