If you are in a field “driven by” closed journals, you are highly unlikely to make career progress if you stay principled as funding, promotions, and so on will depend on publishing where others perceive the work as being good. Maybe if you are an utter genius that brings about a revolution you would not, but how likely is that? However, I do not expect that the audience that matters will not have access to your work in some way, even without open access. If your university is a good one, they will have subscriptions. Plus, there will be networks of researchers illegally passing around documents. Rather, closed access hurts researchers at less privileged institutions and the general public, as they are unlikely to gain access.
