2.Legal restrictions placed on the right of certain industries (or on industries in certain localities) to close down their operations and redeploy their resources in more fruitful ventures. While such measures are designed to protect dependent communities from economic collapse or discomfort they, paradoxically, often end up as barriers to entry.

自相矛盾 以子之矛的以是什么意思？
楚人有鬻盾与矛者，誉之曰：“吾盾之坚，物莫能陷也。”又誉其矛曰：“吾矛之利，于物无不陷也。”或曰：“以子之矛陷于之盾，何如？”其人弗能应也。夫不可陷之盾与无不陷之矛，不可同世而立。——《韩非子》
从前有个楚国的商人在市场上出卖自制的长矛和盾牌。他先把盾牌举起来，一面拍着一面吹嘘说：“我卖的盾牌，最牢最牢，再坚固不过了。不管对方使的长矛怎样锋利，也别想刺透我的盾牌！”停了一会儿，他又举起长矛向围观的人们夸耀：“我做的长矛，最快最快，再锋利不过了。不管对方抵挡的盾牌怎样坚固，我的长矛一刺就透！”围观的人群中有人问道：“如果用你做的长矛来刺你做的盾牌，是刺得透还是刺不透呢？”。楚国商人涨红着脸，半天回答不上来。
所以：以就是用的意思。
