Most people can still go into an office if that's what they want to do.

What's not reasonable in general is to expect others to come into the office to motivate you/socialize with/etc. if they don't have to.

In general, it's reasonable to expect to have some non-home place to work at (whether a conventional office or coworking space). What's not as reasonable is to expect a before-times office where everyone comes in every day.
