Making a profit out of your ideas

Reminds me of the story of the Supersoaker. No patents but a lot of persistence and good business skills. Was able to sell but but spent next 20 plus years trying to collect royalties. Patents are a road bump essentially, enough can be worked around but run the risk of litigation. Patents can be worked around but so can furniture designs. In terms of capital, I have watched quite a few furniture kickstarters fail or just creep over their target. There is no reason for most furniture companies to buy an idea, when they can develop in house or just copy the idea without fear of any legal ramifications. Ideas are cheap. Am i wrong on this?

Is there a furniture version of Betabrand? It seems others have different perspectives, has anyone here attempted this? Got me very curious now.
