I’m not saying trust any random person who calls themself a scientist. Myself included.
I’m saying people should trust reputable scientists at the top of their field. Ideally, journalists should do the leg work to identify these people and give them a voice, and describe why they should be trusted.
That doesn’t happen with nearly all right-leaning journalistic publications, unfortunately, resulting in a huge population not knowing who to trust or just mistrusting scientists in general.
Edit: I realize I didn’t answer your point on freedom of access. I do firmly believe all science should be accessible, because no single study should ever be taken as fact. Science works through repetition, and if you have a study that disagrees with nearly everything else then it’s either a brand new way of looking at things (and will be supported in the future) or is junk (and will be ignored). But just because something is junk doesn’t mean we should prevent people from accessing it.
