Good for you. For us, it was announced as an optional WFH, entirely at the employee discretion (unless they are in a role that has hard requirements of being in the office, like hardware engineering), until October.
To me, that sounds like a perfect opportunity to work remote on a nice beach during the day, and enjoy my time during the evening in a new place, without having to take days off for that. I get concerns of some people like you, and I am not trying to diminish your choice to stay at home. But your take on this is not representative of what everyone else will be doing (and neither is mine, hence why I expect AirBnB to still have that 50% revenue drop), so I wouldn't discount my original point based on that.
At this point I doubt I'll see my office in 2020. I definitely won't be travelling.
