>This makes it appropriate for buildings that are looking to evoke anti-human ideals; churches and monasteries

Have you seen an actual monastery? An actual old church (at least 700 years) kept in its original style?

They are as far as you can get from just utilitarian, to the point that they are impractial in many ways.

Nobody needs, or have any use for, a 120 foot ceiling, except to impress visitors by showing them the glory of God. Nobody needs the entire outside of the building having a row of stone Gargoyles hand carved in the smallest details, but they are there.
