Working from a dedicated space at home is very different from working in a noisy coffee shop or heck even a co-working space, and I wouldn't be surprised if some "no remote worker" policies were built around the idea that the person will be sitting in a Starbucks charging you $100/hr to share their screen with whoever looks over their shoulder.
A remote (where most people work from a home office or some semi-permanent co-working space arrangement) team can definitely adapt to some short term "work from anywhere" changes, but I think the key part is adapt and short term.
I've provided short-notice ops assistance to colleagues from a beach (literally, feet in the sand, under an umbrella) in Thailand using an iPad.
I'm not going to claim I can work from the beach all day every day though.
