I disagree, yes zoning changes could be needed, but the presence of more daytime workers at home in suburban areas creates new opportunities for restaurants, coffee shops, and other conveniences that cater to those workers.
I was implying that the demand would likely be met with strip-malls and residents would still drive everywhere.
There's existing evidence for this: how many restaurants do you see in standalone office parks? A few perhaps, but nothing like what's downtown.
This is also why you don't see restaurants by office parks - if you want to serve the business lunch crowd, it's better to be by something like a Costco with a big parking lot that's mostly empty on weekdays instead of an office park that's all parked-up at lunchtime. Even absent parking-lot efficiencies, it's probably just optimal to be equidistant from all the office parks instead of next to one.
That's the challenge you face, really - out in the suburbs most people would rather drive 12 minutes than walk 7. I think people just see walking as a way to be cold and struggle to carry heavy things, so fuck it.
You will need all of those "unsightly" B2B businesses to underpin the restaurants, consumer retail, etc, etc, that you do want. And unless we invent teleportation the cost of distance is going to put a cap on how far the B2B businesses are from the customers they serve so they are going to need to be somewhat local too.
