For what reason does the president need the power to demand changes to the White House? They only rent it for 4 years at a time. I've never been allowed to deface existing wall art or commission an addition to the building at any of the places I've rented.
It should be a political motion to change the House. Like a security committee requesting renovations to update defenses.
One nitpick: of course the GPUs that don't have RAM yet wouldn't be installed in data centers, irrespective of the existence of those data centers.
The rest of it works: you can have holds on existing RAM/GPUs for buildings that aren't built yet.
