Long answer:
a) Personal info - and how do you determine what is personal info and what isn't. Why should I have the right to know your passwords?
b) Trade secrets, patents were meant to allow people of "reasonable education" to recreate stuff but in reality are designed to prevent that. But providing access to all trade secrets will destabilise many economies.
c) We all ready have access to more "information" than any generation, but people still need protecting form themselves. Whilst libertarians want complete freedom, they conveniently forget that regulations and restrictions (including on certain information) exists on a pile of bodies. The balance between people claiming they have a "right to know" and the dangers of bad actors using sensitive information - or people doing stupid stuff and putting themsleves and others in danger should be struck, and, at least here in the UK seems about right. For now. But like all regulations they should evolve and adapt.
One could argue that, "where there's a will, there's a way" and that if someone really wanted to find something out, they could eventually, and so trying to restrict access to information on say, certain chemical reactions could be seen as fruitless. But it will had another hurdle and raise the bar a bit.
Short answer: no.
