A unicameral legislature can reduce the numbers of the body and thereby keep bureaucracy to a minimum. How that unicameral legislature is chosen should still be fair, whether based upon population or equal representation regardless of demographics. Perhaps things will get done faster with fewer legislators to go along with an executive branch and judicial system.
A unicameral legislature is a bad idea. When there is only one house in the legislature, it is impossible to check what the legislature is doing inside the legislature. If one house is not technically stronger than the other, that will lead to and overpowering legislative body, which will be disastrous.
