"Need" implies agreement on what and how extensive it is. However, needs are in the eye of the beholder, and their perceived extent varies dramatically from person to person. (How much of X does one need?) When we don’t agree on the extent, using the word "need" masks that disagreement. It implies that the beneficiaries' view is the relevant one, even when they are unwilling to offer enough to attract volunteers to supply their needs in the market. The often-different views of those forced to finance those needs are dismissed as irrelevant.
