I think the whole premise of these statements are wrong. If you want to work for money, and go home not bothered with it, then get a job. If you want your whole life ruled by the business, then start a business.
The most hard working people I know have businesses, so starting one in the illusion that it will buy you freedom is very strange. Start a business if you want to start a business, but it will take over your life, not give you "freedom". If you want "freedom" in the weekends and evenings, just get a job.
I think koonsolo has a point, namely that you may start a business thinking “yeah my terms”, but pretty soon the business will determine the terms - and the times.
