Edit: I should preface this by saying I am approaching the question from the perspective of whether or not it is ethical due to the systemic abuse of women in the industry.

I have mixed feelings and would argue professional porn is, at least as it exists in the here and now, is completely exploitative on a systemic level.

If we move past that and limit the confines of the question to amateur/self-owned type paid porn: I would say it requires a society with healthy sex-ed in order for people to have a healthy relationship with porn on a societal level.

On the individual level, context matters a lot.

Personally, I think it should be temporarily banned until we fix the social problems that drive people into it.

I know it sucks for the people who have a healthy and consensual relationship with the industry, but as it is now sucks worse for the people who get exploited and abused.
