Why do you need a guaranteed investment certificate for study permit eventhough you are not allowed in canada

I hope everybody is aware that under SDS scheme you need to have a Guarenteed investment certificate(GIC). This is mainly to ensure your monthly expenses are taken care off.
But as per the new regulations why does one need a GIC or why do we need to apply through SDS scheme.
I am posting this thread so that I will get some reasonable answers to convince myself.

Because the point of SDS is to provide faster processing to lower-risk applicants with secure finances. That hasn't changed.
