You're right that it's not entirely different.

But I'll start with the simple version of the critique. Individual commuters make their decision about whether to make a trip based in part on the time that trip will take (a function of road congestion). Thus, adding road capacity will temporarily lower the cost of a trip, allowing more people to make it until congestion reaches the pre-expansion level. Housing does not have this problem because consumers make decisions about where to live much more infrequently.

As you can tell, "induced demand" is a bad if rather catchy name. To be fair to urban planners, the throughput of an expanded road does increase. However, the experience of using it stays the same or gets worse, and the cost (both $ and space) is disproportionate. Is the pro-transit argument, which I subscribe to.

Of course, the real world includes large real estate firms which are making frequent decisions on housing stock. So I agree that the build-more-housing-and-everything-will-improve crowd is wrong. But I don't think YIMBY/transit and anti-transit are the only choices. The former is a common archetype these days.
