ya totally agree its better to grow your own foods rather than depending on system. if you have control over food you are free , if you cant grow your own food you are slave to system work from 9 to 5 just that you earn money to buy food and when you buy food mostly its unhealthy you not know how its grown as i have seen many videos in which farmers have claimed that they use oxytocin injection in vegetables. Also who knows when food crises start like currency crash then you will be holding thousands of dollars in hand but will not be able to find a single tomato to buy it :) so its better to have control over food rather than depend on system.
