If ownership means you can legally reverse-engineer anything, why did Congress carve out narrow DMCA exemptions renewed every three years instead of a blanket rule? VVision says making the act legal doesn't legalize theft or fraud, but intent is exactly what gets lost. A blanket protection would shield someone defeating a pacemaker's authentication or cloning a proprietary chip layout, because proving downstream misuse is slow and costly. We already have workable exemptions for repair, interoperability, and security research. The law should keep judging purpose and harm, not pretend every teardown is harmless curiosity.
