Two dimensions is certainly better than one, although I note that almost nobody would self-identify as "authoritarian" which makes half of the chart a bit useless.
The vast majority of people, at least in western countries, agree with the basic assumption of (classical) liberalism, which is that "people should be allowed to do what they want, except...". For the most part people just differ on what comes after the "except", whether it's "sell harmful drugs" or "exploit workers" or "use hate speech" or "burn coal" or whatever other grab-bag of activities a certain individual has decided are sufficiently harmful to outlaw.
