There is something disturbing about making something that gives you an

Why ? What's so good about ventilating an attic rather than
using it as a heat trap.

That is like a government basing its budget on
having a tax on prostitution.

Everywhere prostitution is legal it is taxed just like any other
income. I don't think it's a substantial part of any governments income
though.
