Thanks for the kind words and the feedback!
Yes, their crafting is their only scoring engine. They originally also had a toned-down version of the Rat’s Oppression scoring as a supplement to their crafting. It was too easy to fill up the map and ride to victory on passive scoring, and also just wasn’t interesting - why waste cards crafting when you could spend those cards on actions and get more points from dominating the board?
The crafting/paperwork points require you to choose between action economy and scoring economy, which makes for a more interesting play style.
EDIT: Forgot to add, no, no points for removals due to Notices. Bureaucracy is happy to get the extra card, but they want the building slot. Making it less punishing to comply encourages other players to actually give you what you want rather than paying the tax to prevent you scoring a point. Great question!
