In brief, just as we do not ban steroids because they are dangerous, but require that buyers have a valid prescription, we should institutionalize caution in how financial products can be used – and by whom. This option could vastly shorten the list of products that will need to be banned outright.
简而言之，正如我们不会因为激素类药物有危险而彻底禁止之，但要求购买者持有一个有效的处方，我们应当将金融产品如何使用（以及适用于何人）的警告制度化。而这个选项则能令需要彻底禁止的金融产品数量大大减少。
