the social cost that ensue from the use by everyone of sth. that would be fairly harmless if ,say, only the rich were to use it.
句子的意思什么我都知道,主要是ensue from the use by everyone of sth.这句话想不太明白,想请高手帮忙划分下这个句子的句子成分,哪个是修饰哪个的.还有,那个by everyone 可以放在of sth.后面吗?

say,是一个插入语，可以先提出来不管 ， that ensue from the use by everyone of sth. 是定语从句，修饰the social cost ，that would be fairly harmless if only the rich were to use it.是指ensue from the use by everyone of sth. 的social cost， if only the rich were to use it（虚拟语气），那么that would be fairly harmless
