Non-competes are a really bogus way of implementing IP protection at the cost of workers. Fortunately they’re proving nearly unenforceable lately. I’m happy to see more companies losing this battle to prevent individuals from making a living.
I can see the emotions of what you are saying, and on the surface they seem valid, but there's a lot more to it than that.
Starting and running a business can have significant financial risks for the owners. Many employees don't realize that the owners may have signed over their personal assets as collateral to guarantee a business line of credit.
In a business, sometimes payments don't come in when they should, and unexpected expenses pop up, all the while the bills have to be paid and payroll has to be met. The owners dip into the line of credit as needed to keep things running.
But if things don't go well, and the business is unable to repay the credit per the terms of the contract, the bank does have the right to enforce the contract and call in the guarantee on the loan. That's a big burden for the owners to bear, knowing that their family homes could be lost if the business goes south.
Employment contracts don't exist to
"prevent individuals from making a living", they exist to give some amount of protection from insider information being used to harm the business. For the owners that harm could end up harming their families, so it's a big deal to them.
I've been involved in one startup (non-brewing related). All the founders had employment contracts with non-compete clauses. When that business sold us founders were eventually forced out because the new owners wanted to take it in a new direction (which failed btw).
Due to my employment contract they could not dismiss me without cause, unless they paid me a full years salary. They made up some lies and said that gave them cause to dismiss me without honoring the terms of my contract. I shot that down, and they had to pay up. As you can see, an employment contract can also protect the employee, even an owner employee. On the flip side I could not work in a competing business for 6 months.
