There are a number of problems with outhouses. The first is that it
needs to be outside. Also, it requires digging a hole, and later
digging out the waste. It puts the waste below the top few inches of
topsoil where most of the bio-activity is. Generally, they are not
aerobic, so it takes longer for the wastes to compost, and produces a
nasty smell. Since there is no thermophilic phase, it is harder to be
assured that no pathogens remain. A proper composting toilet and pile
avoid all these problems.
