I can't believe how obtuse you're being. Let me try and spell it out:

There are 168 hours in the week.
The average American workweek is now about 49 hours. Add another hour per day for lunch to get the time occupied by work.
Let's be optimistic, and say the average American spends only an hour a day commuting. (Maybe in Little Rock...)
We're supposed to get eight hours of sleep a night for optimum health. We spend perhaps an hour a day on basic personal and household maintenance.

168 hours per week
-49 hours working
-5 hours work lunchtime
-5 hours commuting
-56 hours sleeping
-7 hours personal maintenance
-----
46 hours
about 6.5 hours/day to call our own.

That's the barebones budget for demands on a person's time. Families would add hours more per day. People trying to get ahead by getting an education at night might put in 15 hours a week at it. People short on cash could be working overtime, or two jobs. Many people spend half the day Sunday at church.

The kind of motivated voter you want will fill his/her life up with nontrivial things. How much sacrifice can you demand for the right to vote?

There's more wrong with this. Step back and look at the big picture. To achieve the goal of filtering out casual voters, you're dumping a load of sand in the gears of the machinery that elects the leaders of our government. Isn't that a case of throwing the baby out with the bathwater? And consider, if a long-term stalemate develops, it will be because there are burning issues that people are not backing down from. The system has a contrary response to the importance of an election: Just when we most need to be decisive, the system grinds to a halt.

I'm sorry, but this is nuts. This dog...willl...not...hunt!
