There are two forces at work:

1. Rich cheats for whom complexity is the goal. Reduced enforcement benefits them without the guilt. They can construct nonsensical schemes but if no one ever audits them they get to feel like they are paying what they owe despite being freeloaders.

2. Strangle the baby types: they hate the federal government. They deliberately want to reduce its income to force cuts to government spending (programs and staff). If they can they will cut other parts of the government then use that to justify reducing taxes. Nothing else matters except shrinking the federal government as much as possible via any means possible. These types also enjoy taking any government service that works and people like and making it as terrible as possible to kill popular support thus making it easier to cut the program entirely.
