In this argument, the arguer comes to the conclusion that even if Maple City were to develop strict laws that limit new building construction, the average housing prices will not be affected by these laws. After a scrutiny of the argument, as it stands, it is unconvincing for several critical flaws.
First of all, the validity of the survey is open to doubt. The arguer assumes without justification that twenty years ago's conditions have remained the same as today's. Twenty years is a long time for many things and conditions to change. Like people may make more money now and might need more private space. Hence, only a survey from twenty years ago cannot be the support for Maple City's establishment of strict laws on limit of building new houses.
Also, the argument is based on a groundlessly assumption that the establishment of strict laws on building construction lead to the raised housing prices. It is a typical erroneousness of false cause. The arguer gives no evidence to support that causal relationship. It is possible that many other factors might contribute to the raise. For example, much more people are born and more houses are cried for. As a result, this supply-and-demand issue may increase housing prices. Moreover, overheated economic atmosphere might be a good reason too. Much capital is introduced to real estate, and promotes the growth of housing prices.
Finally, the arguer commits a fallacy of false analogy. Simply assumed that Chestnut City's case is the same as the Pine City's he concludes that laws limiting new construction have no effect on average housing prices, but he does not list any evidence for the validity of that comparison. As we know, the two situations are not similar enough to justify the analogical deduction. Actually, there may exist many differences between them. For instance, they may have different terrains. Pine City is a mountainous area, where limit on building will result in a large increase in housing prices. However, Chestnut City is plain, where much rich people are in pursuit of large house and backyard, which will be the cause of raise in housing prices. And when it comes to the Maple City, the arguer commits the fallacy again.
To sum up, the argument is not well-reasoned and lace credibility. In order to convince readers about his/her argument, the arguer need to take into account many other aspects and make more thorough and convincing survey about the raise of housing prices.
