Looks like a two steps process:

 1) drop vertices that are too close (st_simplify may help)
 2) add vertices where missing (st_simplify)

So one solution would be to calculate the minimum of all distances between two consecutive points in the original polygon and use that distance to build my polygon with equally spaced points. Is this correct? If so, How do I proceed from here? Any ready made solution?

Calculating the minimum of all distances between two consecutive
points could be a useful standalone function. Don't you also need
minimum distance between any two points ? I'm curious about the
use case for the "consecutive only" approach.
