Since friendship frequently goes beyond formal, transactional commitments and provides emotional support and connection without a rigid quid pro quo arrangement, it might be considered a "free" type of exchange. Imagine, for example, that a friend helps you through a personal crisis or other trying period and extends their support to you. You are released from further transactional or contractual relationships as a result of this act of generosity and support, which is provided without a formal expectation of an immediate return. This does not negate the fact that friendships have obligations of their own. Naturally, you might want to return the favor and keep up the relationship—which requires some level of reciprocal commitment even though it is less formal than other kinds of interactions. Therefore, friendship discreetly include a sense of reciprocal expectation and duty, even as it can empower by offering real connection and support.
Take sociologist Pierre Bourdieu's studies on social capital to see how friendship can be "free" yet still entail some sort of reciprocal expectation and duty. Although friendships don't seem to include organized transactions, Bourdieu contends that they do involve reciprocal duties and support networks. For example, Bourdieu emphasizes in "The Forms of Capital" (1986) how friendships and other social interactions are kinds of capital that offer resources and support to individuals but also carry implicit reciprocity expectations.
Taking all this information into account I assume that it would be fair to say that yes, it is sensible to aknowledge that a friendship is a give and take relationship sometimes.
