Agreed - having done a PhD in an experimental neuroscience lab, there's a nonsignificant number of things that nobody else in the world, even in my own lab, can do. I can train the techniques to others, and do, but this is separate from scientific discovery. There are no incentives for someone else to spend their time replicating my work using unbelievably challenging and expensive methods. It just wouldn't work in practice without a more fundamental restructuring of the whole enterprise (which is also necessary but hard).
