It can be ok if everyone is clear, and accepts that you're not really an equal part of the team, but someone who gets tasks and does them relatively independently. That kind of thing can work ok for the right person at the right time.
The problem is if you're trying to maintain the fiction that the one remote person is just like everyone else.
I agree with that. They're effectively a consultant who pops in from time to time and may be on calls. Which can be fine but everyone needs to be clear that's effectively what the situation is whether it's explicitly acknowledged or not.
