If you ban all lobbying, what would government do?  How would it function?  The definition of lobbying is influence on an issue.  That's anything done by anyone.  Good or bad.  That's impossible.

Not to mention that politicians aren't going to know the first thing about farming, technology, or market issues.  Generally these people have law and political sciences degrees.  

So farmers groups pay money to lobby congressman to look after their interests and suggest regulations all the same as an electric company or a social media conglomerate. 

For instance the price of eggs is so high right now because there is an FDA regulation that requires a farmer to kill all their chickens if one of them comes down with avian flu to prevent spread to humans even though human transmission is rare.

So a couple decades ago an uninformed lawyer from California decided that they could play up fear of bird flu from China and passed regulations that are only now having profound effects on the market.  At the time though they likely ran for reelection on how they saved lives by passing these regulations.
