Just my two cents, but humans are social creatures and I think when we help each other we have the best chance for success. This isn’t me saying not to grow your own food as much as you’re able, but eventually everyone’s individual skills run dry and we rely on the expertise of others. If I ever need medical treatment, I’ll need a doctor, for example. Even medical professionals themselves would need a doctor depending on what’s wrong with them. Long-winded ramble all to say, farm for sustenance, but there’s nothing wrong if you need to rely on the help and expertise of others along the way.
