Markets only solve the information problem, they don't address the decision problem (given unlimited knowledge of the present, how do we optimize the future? -- an intractable problem) or the measurement problem (were the decisions we made in the past good or bad? What was the GDP in 2011? -- a very hard problem). Applying markets to problems other than information problems won't work. Using markets to "deci[de] on a political party every few months and that political party makes decisions" isn't bad (just) because it's a one-party state, but because nobody--not even new Soviet man or Madison's government of angels--is actually competent to make the decisions that would be needed to make central planning work. Democratic or Plutocratic or Market-inspired or AI-based central planning all don't work because the problem is central planning, not the method of choosing the planners.
