It is not a legal requirement, it is a suggestion. There is NO LAW stating that you MUST self-isolate for 14 days on returning from abroad.
In fact, it is pure security theater/dog-n-pony show. The chance you get COVID-19 from your local supermarket is probably higher than travel with face masks, social distancing and adhering to personal hygiene.
