Not got the energy for that one. But briefly:
Money is a representation of an obligation between parties - a quantification of a debt (and yes, of course, that involves quantifying the value of goods, work, etc). But this representation has its utility - it is in many ways a good trick, allowing the transfer of obligation across society: the simple 'A mends B's roof today, then B fixes C's teeth next week, then C fixes A's plumbing the week after'. The whole process is one of debt taking out and debt repayment as obligations shift. Money allows the transfer of obligation across time and space.
