2. However, if you want to run lower pressures (for example for some type 1/2 gravel riding), but don't puncture flat, you still want to avoid pinch flats. Hence TL then becomes advisable.
3. So if you're not concerned with puncture flats, and want to run TL and some lower pressures, why bother with the sealant? As much as you'd flat with tubes, you'd flat with this setup, and you could still carry a tube for the rare flat? The Vittoria thing adds a modicum of backup that could allow you get home to deal with cleanly.
and/or
4. If you perhaps are also a rider that bought one of those 'all road' bikes (Caledonia etc), you might have a separate gravel/wide setup wheelset for infrequent rides of that type, that if you infrequently use, you don't have to concern yourself for longer period of time storage with installed sealant. Or you don't have a separate wheelset, and want to somewhat frequently swap between road and gravel tires on your rims (eg. 25s to 35s) -- I understand an inconvenient proposition if sealant is involved.
That’s the cool thing about this period in time: options! We’ve got access to more wheel setup options than ever before, allowing us to not only fine-tune the ride quality, but also to finely manage risk. New tube types like Aerothan, Tubolito and Revoloop should be considered for someone considering to run tubeless without sealant, because they offer enhanced puncture and pinch resistance compared to butyl or latex, better accommodating low pressures and allowing roadside serviceability for continued normal riding in a way Airliner does not.
