I'm not a farmer, but do own part of a small business. So I can maybe comment on it from that perspective.
To be successful at a business (any business) you have to have 2 things:
1. domain knowledge - you have to know how it works, what to do and not do, good network of customers and vendors, etc
2. business sense - financial know-how, access to capital, good judgement, etc
Most small business people have a lot of 1, and a little of 2. And they do OK.
Going the other way, you better have lots of capital to burn while acquiring all that domain knowledge.
If you really wanted to get into farming as a business, I'd say your best bet would be to find someone with lots of #1, and bring your cash, business acumen, and even more cash -- and partner up. Then over time learn the business from them, and take it over.
I would probably say the same if you wanted to open a pet store or a sandwich shop with zero experience. Go work at one for a few years to figure it out. Then open your own.
