The commodification of housing means bringing housing to the market, and mainly relying on market regulation to solve housing problems, it also means greatly reducing the burden on the government and reducing government intervention in housing. However, the government must not take a big picture. In the process of housing commodification, the social welfare component of housing is gradually decreasing, and operating profits will gradually become the target of chasing. The unreasonable phenomenon in the old housing distribution system is likely to be affected by some new ones. Reasonable phenomena have replaced them. During economic turbulence, new unreasonable phenomena also threaten social stability. When market regulation is weak, government intervention becomes particularly important. What is the main point of this passage? ['Commercialization of housing is an inevitable trend.', 'After the commercialization of housing, the government will no longer directly intervene in the housing industry.', 'There will be unreasonable phenomena after the commercialization of housing.', 'Government still needs to step up in the process of housing commodification.']
