We eat food after buying it after it gets harvested with hard work, cooked, and served. Though we give money, but we dont harvest, or cook. After all, we will give money but not the hard work when they did to give food to us. so, we robbed something and compensating that robbery. It is legal. To question it, is ' illegal in minds '.
Except the real labour who puts the plant in the field has some right to eat it. none otherwise.
Is that earth gets food by itself ? or will it have to reimburse that sunlight to the sun after sometime ?? ( One Lakh question marks. This could become a theory. Nations could easily put 'sunlight tax' if this idea is leaked.)
