Very variant spell magic

Well, then it comes down to how common Magery is. Unless mages are extremely rare, I suspect the magic healer is still going to make more profit and impact by making healing wands.

Add to the that the need for a fairly rare aptitude (Magery 2) and you have a meaningful barrier to entry.

If magic items are the primary means by which magic is done (as you stated in post #1), and most magic items were created by the end user (as you stated in post #23), this means most practicing mages have at least two exceptionally demanding skills at 15+ (Enchant and whatever spell(s) they primarily use), along with all the prerequisite spells (which needn't be at any level of competence, just whatever they get to by investing [1], unless your setting follows different rules than the default in this regard). So, the Magery 2 part of the character may be exceptional and rare amongst mages, but the rest is clearly the norm for mages in your setting.
