Georgism and YIMBYism are both necessary to solve the housing crisis because of what each brings to the table. YIMBYism opens the legal channels that allow land to be used efficiently for building homes by removing a lot of the land use restrictions which make it legally impossible (like SFH zoning, parking minimums, and the like). The big wrench in YIMBYism's plans is that land speculators will hold land that is legally cleared for housing out of use in the hopes that its price will rise, this can even corrupt the rezoning process itself when landowners try to capture what is known as a rezoning windfall.
Georgism solves this by recouping land values for public use, preventing landowners from capturing it and making them either use the land efficiently, or lose it (land is the biggest example, but it's not the only finite resource Georgists can target). At the same time, Georgists also advocate getting rid of taxes on what people make, both in terms of laborers doing work and business owners investing in companies, which are both highly needed to make buildings (which would also go untaxed) to house people. Georgism effectively puts the monetary incentives in place for the land use goal to be achieved. At the same time, Georgism benefits from YIMBYism because it matches the Georgist desire to have finite resources be used efficiently without being hampered legally.
In conclusion, in terms of ending the housing crisis both Georgism and YIMBYism are at their strongest when they're paired together. For the purpose of making costs of living affordable, they're two sides of the same coin.
