I don't really understand where people are coming from on this whole "barrier to entry." I think it's safe to say that doesn't apply here. Not being able to enter the market due to not knowing how to manage doesn't make something a "barrier" exactly. Maybe a specific PART of the market, but you shouldn't be running into issues with not being able to afford the tax of what you're selling anyway. You work your way up, like with most other things.
