Profit is the main goal of all economic activity. Economy is an activity of making and moving money around, which is only possible if you make profit.
Money is an instrument to facilitate this, as is profit. Neither of them is the end, they are means. They are also not the only possible means.
Also, you can definitely move money around with making a profit. How is that impossible? Are you telling me no money changes hands if I, e.g. sell something at a loss, or to break even.
Please, think about it for a second.
