A 'national lab' does not have anything to do with 'nationalisation'. Nationalisation means to take over an existing privately run lab, whereas a national lab can be established from scratch without even the hint of a takeover of any private organisation. In the post you replied to there was zero suggestion of nationalisation.

That said, nationalisation is sometimes the correct move as the opposite of privatisation which is also sometimes the correct move, so attaching labels like 'socialist' to it to tar the policy is not productive (just as tarring something as 'capitalist' also does not beget good thinking about policy).
