My point is that no congresspeople would sign off on a law that would stifle innovation to such a degree. Customers should be given the tools to make better decisions regarding the repairability of products if they so choose to factor that into their purchasing decision, but if it means outright stopping purely positive improvements like faster CPUs then it's both harmful to consumers and not a law that would pass congress.
A lesser extreme is the southbridge/northbridge and how CPUs are becoming SoCs. If that fails, you pretty much have to buy a new CPU, when previously you could technically replace it if you wanted. Would have such a version of the R2R law prevented this?
