Lots of people are justifying this as if it's logical, but ultimately rules like this are the result of bureaucracy. Most likely your office is still WFH because nobody cares. Maybe nobody else wants to go back, maybe the company saves money, maybe someone high-up is still nervous about covid, probably a combination of those three. It's similar to how at most places there are signs everywhere saying "please remain 6 feet apart", "due to covid ..." and people don't even follow these rules. Nobody bothered to take the signs down. Ultimately if you're vaccinated, there's not really a point to masking or social distancing. The exception is masking in public areas like supermarkets and doctors' offices where sick people have to go and it's not a big deal. Or in areas where there is hospitals are overflowing and there are too many unvaccinated, like earlier in the year.
