Rent not being competed away

countervailing a named mechanism, not a conclusion

These names own a bottleneck that does not bind them AND are spending at or below the 25th percentile of their own capex history. Capacity that is not added is how scarcity persists — the mechanism behind every durable margin in this industry, and the opposite of rent converting into capacity.

coverage

1 of 3 testable rent capturers (14 total, 11 carry no matched capex history). A short list here is not evidence that the others are expanding — most simply cannot be measured.

Arguments about this mechanism

None yet. No thesis names this mechanism’s subject, which is a gap in the bank rather than a fact about the mechanism.
