For some people this isn't a problem. I personally don't mind at all walking through a messy house to get to my computer. But I know many people who easily get distracted - who start to watch TV, or run the laundry, or do other things. The more that you are drawn away from your task, the less work you will get done - and the less success you will find. I know many people who tried a home office and then had to rent a "real" office space because it was the only way they could make it work. If you are addicted to the TV, or focussed on a clean house, this might not work for you.
