Paul by no means denies the right of a minister of the Church to material support from the community in which he carries out his ministry. And yet the apostle himself never used such a right. Not because he considered his ministry unworthy of compensation. He was simply convinced that his apostleship had to be absolutely free from any external, social attachments. Paul earned his living in other ways, without resorting to help from the church communities where he had to spend time and carry out his ministry. The apostle himself speaks of this refusal as his personal choice, not considering it a universal norm for ministers of the Church.
With regard to himself, Paul believes that refusing any compensation or material support from church communities gives him a spiritual freedom and integrity that he would not otherwise have. What does he mean? No genuine ministry is ever merely outward activity, action, or work. It is always derived from a person's inner state, an outward manifestation of his spiritual life.
But from the point of view of society, even if that society is a church community, the matter is precisely work that can be weighed, evaluated, and paid for. Of course, here we are not speaking of ministry as such, but of its outward manifestations; only they are ever weighed, evaluated, and paid for. It is these, unlike the ministry itself, that can be weighed and evaluated and paid for.
As the poet very rightly observed, "inspiration is not for sale, but a manuscript can be sold." Something similar can be said about the payment of a Church minister's labor: it is impossible to sell the ministry itself on the labor market, but some of its fruits can fully become a commodity there. In that case, however, the minister himself will be forced constantly to keep that same market in mind.
Of course, under normal circumstances it will not determine the ministry, but there is no doubt that, for the minister, taking account of the situation there will become an additional attachment to society. This is exactly what Paul wants to avoid. He does not consider it possible for himself to depend materially on his ministry even to the slightest degree. The apostle understands perfectly well that this is his personal choice, which cannot be recommended to everyone as the only possible one, but he himself sees his ministry only in this way, as he says directly and openly.
