> When the principal danger is to oneself I think restrictions are rarely justified, but when the consequences are borne by others, I think it's more justified.

I think this point makes broad sense but needs refinement. For example if we assume there is a vaccine available that:

- Reduces personal injury - Does not prevent transmission

Using the above logic would mean that after taking the vaccine restrictions are more justified because the burden of the disease has shifted. I don't think that's what you intended and probably means that there still needs to be reference to absolute harm and taking reasonable minimization measures.
