The Friction Merchants — Summary
Caroline has explained how Visa works hundreds of times. The authorization request, the settlement cycle, the interchange fees nested inside fees. She explains it again at a dinner table. The people listening have used the product thousands of times and have never thought about it. On her desk at the office: a glass jar of foreign coins accumulated over twenty years of international travel. She keeps it for the weight, the sense of holding something real.
Every financial intermediary was built to solve a genuine problem. The bank intermediated trust between strangers. Insurance pooled the unpredictable. The correspondent banking network moved value across continents. Each charged a fee that was, at origin, the price of the problem it was solving. The toll booth economy did not begin as rent extraction. It began as value creation. The problem is what happened next.
Toll booths outlive their function. The financial intermediary built to solve the trust problem continues charging for trust assessment after AI has made trust assessment cheap. The persistence mechanism has three components: switching costs that make change expensive even when the alternative is cheaper, regulatory capture that shapes the compliance environment against new entrants, and information asymmetry that conceals how much of the fee is now extraction rather than service. Caroline’s industry understood all three. She thought of them as competitive moats.
AI is dissolving the frictions that justified the fees in three cases. Payments: real-time fraud monitoring is now far more accurate than what interchange pricing was built to cover, while the fee has remained constant. Insurance brokerage: AI agents can analyze coverage terms across carriers with thoroughness no human broker achieves, eliminating the information advantage the commission was priced for. Mortgage origination: AI credit assessment is more accurate and less biased than loan officer judgment, though the origination fee persists.
The technology that makes friction assessment cheap also makes the toll booth visible. A consumer using an AI agent can now see the effective spread, the fee decomposed, the comparison adjusted for terms. The opacity that made toll booth extraction sustainable is dissolving. But the toll booth does not disappear when AI makes it visible. It becomes a stratification mechanism. The consumer with the agent who can interpret the comparison, who has the financial literacy and bandwidth to switch, routes around the toll. The consumer without those things continues paying.
Financial intermediaries are not dissolving gracefully. They are buying the protocol companies that threaten them, lobbying for credit assessment standards that require human review, using AI to improve their own underwriting while opposing the consumer-facing tools that would reveal the improvement as extraction. What the friction merchants are actually selling, in the transition, is regulatory position. The technical moat has dissolved. The political moat is stronger than it has ever been.
Caroline puts her card down for the dinner bill. The authorization runs in under a hundred milliseconds. The infrastructure is real. The jar of coins is real, solid and specific, each one a particular place. Their value is uncertain and their weight is not. The question the jar keeps asking is the question the industry hasn’t answered: what is the infrastructure for now?
