The left vs right dichotomy doesn't have too much to do with collectivism vs individualism. For example, social conservatism is a right wing idea, but it is highly collectivistic (prioritizing social mores over individual freedom).

Left libertarianism typically means free market economics + democratically organized and owned workplaces + social libertarianism (free love, free religion, free drugs etc). Right libertarianism is similar, but emphasizes contractualism instead of democratic control.

Left libertarians typically scoff for example at corporations for their limitations on the personal freedoms of the workers, viewing it as a form of slavery.

The very opposite.

"Libertarianism originated as a form of left-wing politics such as anti-authoritarian and anti-state socialists like anarchists,[6] especially social anarchists,[7] but more generally libertarian communists/Marxists and libertarian socialists"
