I understand the key differences between antialiasing and point sampling, but I don't fully understand when we'd use antialiasing over point sampling, or are they meant to be used together in accordance? Anti-aliasing minimizes the distortion artifacts but can't point sampling achieve this as well

@rishiarjun They are meant to be used together: anti-aliasing is pre-filtering (blurring) followed by point sampling.
In theory, it is possible to have scenes with infinite frequency content, and so point sampling alone will always introduce distortions. For example, you can create a chirp signal which has frequencies that grow without bound.
