Because it would occasionally overflow and drown a lot of people.
Answer:
The most correct statement is "It is theoretically impossible to create a portfolio that offers a positive return and a standard deviation of zero".
Explanation: A portfolio that offers a positive return is a portfolio that has profit. This type of portfolio has assets which positive returns are greater than the negative returns, this means that the difference between the assets in the portfolio must be a positive value that is greater than zero.
Standard deviation helps to measure the dispersion of the assets value in the portfolio. If the standard deviation of the portfolio is zero, that means the assets with negative returns are equal to the assets with positive returns, therefore profit or loss are not made in the portfolio. The portfolio is not going up or down. Therefore it cannot be referred to a positive portfolio, because it is not making profit.
Government spending accounts for a huge amount of the economy — some 40% or so in many modern economies. It’s not a matter of whether the government should try to influence the economy — it inevitably does. The question is in what ways it should try.

Famous Hayek quote that needs mentioning in this sort of thread:
The curious task of economics is to demonstrate to men how little they really know about what they imagine they can design. To the naive mind that can conceive of order only as the product of deliberate arrangement, it may seem absurd that in complex conditions order, and adaptation to the unknown, can be achieved more effectively by decentralizing decisions and that a division of authority will actually extend the possibility of overall order. Yet that decentralization actually leads to more information being taken into account.
