If a low powered game is the thing you and your players want, then go for it, but don't BS yourself into thinking that starting the players off with fewer resources somehow makes the roleplay purer .
That's elitist garbage.
It's the same game with smaller numbers.
The GM has the same challenges in crafting a compelling storyline, with a solid tone, interesting flavorful NPC's, and "level" appropriate challenges. The players can still choose how to approach the situations presented, how to go about overcoming the challenges, and decide whether or not to power/meta game within the allowed rules, or whether they want to go deep into character interactions or ignore all the "box text" and kick in the door to roll dice.
Starting SP/PF means nothing to any of that.
