I know, in theory you can have a law for everything. For example, in the Soviet Union basic electronics such as radios were restricted and you were not allowed to tune your sets to western stations.
I don't think a database or a computer murdered or kidnapped anyone. I mean, a computer which runs the B-tree algorithm and talks with the rest of the internet according to a bunch of loops/if/then/else statements is not exactly an assault rifle.
But yes, everything can be banned eventually. We'll just go back to living in the cave.
