The less accountability you want, the less freedom you can have. The more you want freedom, the more accountability you must take on.
Companies sheltered from the market (low accountability) in turn have little freedom to innovate because they are hampered by regulations.
Those most free to innovate are most immediately accountable to the market.
You can raise capital to put a buffer between the business and the market, which reduces your accountability for a while, but it also reduces your freedom, as investors want things and prohibit things.
