The practice of using healing magic without extracting payment is what's prohibited.

The issue there is that the temples' primary source of income is their provision of healing with an appropriate fee. If adventurers went about and healed people without charging them for their services or outright directing them to a temple then they would be stealing the livelihood of the temple's healers.

The loophole for adventurers is that they can practice healing magic on their colleagues without repercussions.

If you've read Chapter 8 and know about the workers then you'd be enlightened by the practices of Roberdyck, the healer in the party of four called [Foresight].
