Must one obey the government ban on selling petrol at grocery stores or other unlicensed premises?

Summary

Selling petrol is originally permissible because it is pure and beneficial. However, when the government sets regulations, citizens must comply, especially given safety and pollution concerns, and selling at unlicensed premises can become forbidden under siyasah shar'iyyah, based on sadd al-dhari'ah and maslahah mursalah. People are discouraged from selling petrol without a valid licence, except in urgent cases such as a stranded vehicle that has run out of fuel or a distant petrol station, provided safety is observed, for example by using suitable containers.
