The primary purpose of the ranking system is to make players play as much as possible. Ranking points get you seeded, and they get you into the main draw rather than qualification (and I assume they get you into qualification rather than the ITF circuit). Creating some sort of plausible rating is essential, otherwise the rankings would be regarded with derision, but that's certainly not what they are for.
