In the end it's more a financial thing IMO. When you just entered a 10 or 15 year lease right before Covid hit, you're now stuck with paying 7 years for an office you're not even using - that's objectively bad for any company's financials (and in some cases, bonuses for decisionmakers tied to stuff like "cost per employee").
The other side of rentals, the entire REIT industry, has it even worse, they're in pure panic mode: there are a lot of projects that got completed shortly before, during or after Covid... and that now lack renters while interest rates for refinancing keep going upwards as the free money ran out and central banks imposed serious rate hikes.
And if that's not enough, cities also have a problem... when people don't commute by car, they don't pay road tolls, endangering their financial calculations. When they don't commute by public transport and don't pay subscription tickets any more, the transport authorities get into financial trouble. When storefronts of bakeries, coffee shops and other ancilliary services for office drones get boarded up as no one is in the office any more to buy all that stuff, blight sets in.
Side industries are also hit: when people demand fast Internet at their homes to work efficiently or utilize other stuff such as water, electricity or trash more (because they'd have to expand their long-outdated, barely adequate service), utility providers have to invest serious amounts of money. Car insurances tied to distance driven per year lose money. The list of economic activities directly tied to an economy dedicated to people commuting from their homes to their office is really fucking long.
Hence, there are massive financial interests putting up serious efforts, both political and medial, to push for people to come back to the office even though largely only the already uber-rich profit from that.
