A few problems with that:
1. You've got to spend extra time setting it all up.
2. Then your setup may break at any point when they introduce more anti-piracy measures.
3. You can't just sit down after a hard day, press one button and make it work immediately.
4. Limited content.
5. Quality issues.
6. Unnecessary faff.
7. One day you may end up in legal trouble.
8. Probably many more other problems which I can't even be bothered thinking about.
At some point you wake up to a realisation that sure - you can make it work, but your time is better spent elsewhere, on things that actually matter.
