Votes—primarily upvotes—are an important signal to the system. We use post scores for all kinds of things, including surfacing relevant posts to new members and for telling Google which pages are important. Historically, the biggest problem that we have is that people are not voting enough! The more votes, the more signal that the system has. We currently disallow downvoting until you have 200 reputation, and limit everyone to 15 downvotes per day at a cost of -2 reputation for each down vote that you cast. Are you proposing raising the reputation requirement for casting a downvote? We also have a separate upvote limit per day for new users of 15 votes. Another option would be to lower this to something like 5 votes per day.
