Well look at it this way then. Rather than trying to get a bunch of spells together people are instead pushed towards freeform casting. If they want to be able to reproduce the same effect again and again they can put the time and effort together to get a spell that they've worked at. However, generally speaking until the game is sufficiently old most people will have maybe a spell to kill someone, and a spell to do X. It'll take them time to build up, a lot like the original SM was really where collecting spells was difficult and a sign of prestige.
It'll also make guilds and friendships that much stronger. If someone can instruct you on how to do a certain thing you'll learn it much faster.
