  We can see a dilemma that arises from the above considerations. If tacit consent genuinely arises from voluntary residence in a reasonably just state, then it appears that the interpretation of the person's residence does not take account of what many consent theorists have thought was essential to consent theory, namely the personal reasons of the subject in deciding whether to consent or not. On the other hand, if those personal reasons are ones that the subject may properly take into account in deciding whether to consent, then the interpretive move required for voluntary residence to generate obligations in all subjects of a reasonably just state cannot work. It cannot work because subjects may have personal reasons for not consenting, which voluntary residence does not rule out.
