I'm assuming your reasoning is that LW people are, or at least are capable of, spending their time/effort doing more valuable things, so time spent voting (including time spent becoming an informed voter) is a net loss.

If that assumption gets widely implemeted, the end result seems to be that only people who don't do anything particularly valuable with their time vote.

Am I following your reasoning correctly? Or is there some other aspect of LW people (like being more likely to work on x-risk, or being more likely to be mathematicians, or something else) driving your reasoning?
