I think you're just grasping for straws.
All it means is that the Enclave's day to day tech before its demise hadn't changed in over 200 years. The only thing the Enclave changed was the Power Armor, everything else had no real reason to change, a desk is a desk no matter what you do, so no reason to change it. Plus the Enclave's command table isn't exactly new technology. If you looked at Operation Anchorage, General Chase was using a much similiar situation desk in his tent.
As for the bunker, it was likely a refueling depot for their crews flying between various outposts around the region/country.
