If ports are unpriviledged, why can't I access them if I am root in a namespace?

namespace port network-namespaces unshare

                          I've run sudo sysctl -w net.ipv4.ip_unprivileged_port_start=1. However, sudo ip netns exec myvpn unshare -r python -m http.server -b 127.0.0.1 2 does not work. Strangely enough, this does: sudo ip netns exec myvpn unshare python -m http.server -b 127.0.0.1 2. Why?

**EDIT**: However, both sudo ip netns exec myvpn sudo -u $USER unshare python -m http.server -b 127.0.0.1 2 and sudo ip netns exec myvpn sudo -u system unshare -r python -m http.server -b 127.0.0.1 2 don't work.
