@bob Thats not accurate though, money has existed for thousands of years, being paid to do a job has existed for just as long, and we all know slavery was popular for thousands of years too. All the points you claim are recent "money, wage, slavery, etc" are all ancient and wide spread.
@bob Even the farmers still bought their tools and their clothes from vendors. Most used some form of currency to do this. You could argue much less so then modern day farmers perhaps, but the capitalism was always there. Capitalism isnt about the quantity of money exchanged, but rather the free market which allows you to do so. If fewer people participate in the free market it isnt any less of a capitalism, not unless that effect is brought about through some sort of regulation.
TL;DR even farmers had money.
All economic forms exist simultaneously, but in differing ratios. Use of money, wage slavery, etc, all only really gained any significant prominence within the last few centuries.
