Steerer Stop Band – weakens steerer tube if removed?

Questions:

1. Does the ‘Steerer Stop Band’ also meant to reinforce the steerer tube for added strength?

2. Does it weakens the steerer tube if removed?

3. Does the limited right-turn angle pose a danger for you?

Bonus question – Does the similar one in T-Line also considered an essential item for ‘steerer tube strength’?

The enginerd in me visualise the torsion and deformation stresses and I can’t seem to see how this little clamp aids in strengthening. I’d even consider it weakening as it is adding tension to the steerer tube, resulting in a stress point rather than a strengthening point. However very negligible.

This argument is against the logic from mountain bike mechanics’ experience of needing such a sleeve/clamp to strengthen the steerer tube. Is it still a thing these days? Especially for tapered steerer tube.
