1. Right to repair is awesome.
2. Imagine taxing products in a way that is inversely proportional to their reliability. Do you make RAM or products that use RAM? Standard DIMMs and products that use standard DIMMs are taxed at a lower rate than products that use soldered on RAM.
Sell LCD screens or products that use them? A standard connector and standard mounting holes (as measured against products sold in that category) lowers your tax bill.
If your parts have to be coded to the machine, every one is taxed as a 1-off product interface.
Let's tax 1-off products at 100%, and drop that to 0% at 1 billion copies that use that interface.
3. Have you ever used multiple terminals on a Linux PC? Windows used to have Windows Multipoint Server that did exactly that. It reduces waste and makes more efficient use of resources. Many households would benefit from a powerful workstation or gaming PC in a family room, with multiple screens, keyboards, and mice. Standard swiveling monitor mounts allow a single-seat triple-monitor setup to morph into 3 separate seats so everyone can get their work done at once.
Imagine mandating multi-point support on all software.
4. Lots of PCs go into landfills only because companies like Microsoft refuse to support them. We all see 6th Gen Core machines going in the trash because the are not supported in Windows 11. The easy fix is: If a product has 100,000 installs that are willing to pay $10 per year for updates, then security updates are required as a national security issue.
I'm sure my numbers need some work. These are just ideas.
