You're probably correct in many (or even most) cases, but I still believe that it's too difficult for some people, for two reasons:

1) Some people are under more stress than others, and are less able to summon the effort to vote. Admittedly, this does also include people in rather different circumstances, such as elderly homeowners who become unwell at election time (especially after the postal vote deadline).

2) Voting arrangements aren't uniform between countries (or even within one country), and travelling some distance to a polling station and then queuing to vote is a burden some voters might experience much more than others.

The vast majority of states offer a multitude of early voting or absentee/mail in voting options. As far as uniform regulations between counties, who cares? Each person is only supposed to vote once, and in a single county. Learn your local regulations (easy as this is well documented) and follow them.

Further, you won't ever come up with a system that is 100% inclusive, secure, reliable, and economical. That should never be the goal since it's not achievable or necessary. Covering 99% of cases is good enough.
