Hello welcome to OSM. The features you removed in this changeset are valid. If it exist on the ground should not be removed, regardless if its private or public, behind gated or not.

Please read for more info:
osm.wiki/Why_we_won%27t_delete_roads_on_private_property

The correct way to handle this in OSM is to use the tagging system. access=private seems to apply here.

I have restored the roads.

Removing features that are valid is considered Vandalism. Please read more about OSM before making changes.
