Creating an inset or an inset copy of a flat edge loop shape

Support Modeling
#1

Below is an object that was converted from text “2” but with high resolution. The black surface is not filled black but black because of all the edges. Anyway, I selected the outlining edge loop. Now, can I create an “inset” version of the loop? That is, a new edges that looks like “2” but thinner in all directions; Not a scaled-down version of the same shape. The new edges do not have to be the same object, a separate object will be fine.

I would not want “Limited Dissolve” because it makes the edges not smooth.

Select outer edge, invert selection and delete verts. Select outline again, F to fill, then inset.
With that density of mesh it will probably be beneficial to remesh it first.
