There is a difference between a collection and an exhibition.
A difference between strolling and scrolling too.

A collection can just be a pile of paintings in a cupboard
or a bunch of photos in a drawer

An exhibition is a display of selected pieces arranged in a space.
It is important to leave space between works so that they do not detract from each other, unless the tension or the harmony between them is the desired effect.

Exhibitions can be designed to display the individual pieces or to express the intent of those who arrange the display.
So perhaps the role of the curate would be to paint the walls light green and encourage people to click the like button?

I would say that the desired effect of an exhibition was to alter the mindstate of the viewer, to inspire, to enthral, to entertain.
But others would say that their job  was to sell, to promote, to market.
Some would feel that their aim as curate was to raise their own status.

Organising and arranging such a thing should result in something which leaves people wanting more, and feeling refreshed rather than getting halfway and saying "is there much more of this to go through". It is about composition and entertainment, and part of the process is that the viewer takes time to reflect on what they experience. 

Space is needed to achieve that.
