Markets are but one mechanism for trading resources. Not all econ. Economics is about analyzing how preferences are satisfied given the availability of limited resources. These preferences may be for certain things that cannot be consumed in individual units, e.g. a sunset. You cannot find the value listed on the invoice, but it is certainly there.
Reputation has a public good quality that prevents it from being traded in a market economy.
For example, they vote to maintain the right to vote on issues in the future which may be more critical to them. If everyone quit voting then we wouldn't need to have democracy. That people feel like they have less stake in the long-run decisions by gov't may explain why turnout is dropping. The more sophisticated analysis I discuss is done by economists. That seems to make it economics.
