No, why do you think it’s reasonable that be a requirement to be productive?
Be patient, kind, and spend an extra minute writing a more detailed email that is helpful to your colleagues. If you're a manager, give them the right tools and empower them.
But this is completely orthogonal to whether the work is in an office or remote.
If people are bad at writing, they can get better at it, like any other skill. I have a bad memory for voice/video conversations, so my preference is to always have a written email to go back to for reference.
But I'll still attempt to do what my other team members are comfortable with.
