@Ionus,
Miracle rice, hybrid variety developed by traditional methods in this country over a genberation ago, significantly increased yields and reduced starvation throughout Asia soon after it was introduced and it thrives still. Today plants genetically modified to avhieve the same things, but by more precise and reliable means are prevented from application in countries that sorely need them by threats of economic reprisal by welloff European countries with highly regulated and protected local agricultural establishments.
You are entirely incorrect in your assertions about the Cultural Revolution and the USSR, etc.. While the motives of the leaders (which you can't possibly know for sure) may well have been to enhance or increase their control, the fact is popular acceptance was indeed achieved by way of promises to achieve the "betterment of all" or a "workers paradise" through these revolutions and only after generations were sacdrificed to totalitarianism and poverty were the emptiness of these promises made clear.
My objection such laws is based on my dislike of totalitarian methods of governance in which "Everything not prohibited is mandatory" to borrow a phrase by T.H. White.
If people choose to waste less food and profit by doing so, without adverse effect, others will imitate them. What is gained by forcing them to do so? Freedom of choice is important, and its value is best recognized after it is lost.
You are the one figurtively sitting on a high horse and proposing to dictate to others, not me.
