Hitler’s flak towers are not going anywhere. There’s other 20th century buildings which can last a thousand years with occasional maintenance, but those flak towers, nothing will take them down.
Most very old buildings that survived to this age, survived because the locals had a use for them and maintained them, or because they had a pyramidical shape. The colloseum was a castle, the parthenon a church, … Without that usage, we’d only have the foundations and a few basements left.
This seemed like such an arbitrary law that I went looking for it and apparently it’s a small committee (4 persons*) rule that was poorly substantiated. The rule itself has been shot down by an appeals court in 2023, but the industry obviously had already set plans in motion to change their product line ups.
"On September 13, 2023, the U.S. Court of Appeals vacated the CPSC’s rule on custom window coverings. The court agreed with WCMA that CPSC failed to provide an opportunity to comment on the underlying incident data, conducted a flawed cost-benefit analysis that ignored the enormous harm that the rule would have caused the multibillion-dollar custom window coverings industry, and selected an arbitrary effective date for the rule. The CPSC acknowledges that the industry will need at least 2 years to develop completely new products. So the s
ix-month effective date would make it impossible for the window covering industry to create proven safe replacement products."

Edit to add: that rule that lost in appeal in 2023, was from November 2022, so maybe it does go in effect in november 2024, since it seems like that timetable was the biggest issue for the industry. Just speculating though, can’t look it up atm.
