This is technically correct, and running a lifestyle business can suit some people.
But running a business is stressful because at the very least you have to deal with taxes, accounts, cashflow and sales that are more complex than being an employee. If you take on even a single employee it's another level of complexity on top, and you have to make payroll every month without fail.
For me at least it was better to do it for a few years with an exit in sight (in my case it went out of business, oh well!) rather than knowing that the stress of finding payroll every month would go on and on forever. And that means going for growth or bust, having a co-founder and all that.
You don't have to have co-founders, you don't have to take VC money. You don't have to do anything period.
It is your company, you run it and if somebody else wants to run it, they can either fire you if they have means to do it or buy you out.
