Piracy: ꜱᴀɪʟ ᴛʜᴇ ʜɪɢʜ ꜱᴇᴀꜱ

Art/media is part of the world/history

And they are created by human beings, who have every right to decide what their creations are worth to them and under what terms other people can use their creations. I whittled a pretty cool dragon out of a stick once. It's technically part of the world/history. That doesn't mean anyone else has a right to it.

Let us pay for things and have them, it's that simple.

Absolutely, if I am willing to sell you that thing for the price you are offering. If I am not, then the deal doesn't go through. That is how deals work. You cannot rent a car for $60/day and then decide "actually I'm going to keep this forever." That was not the deal you agreed upon.

Once it cannot be sold it should be publically available if someone who has it wants to make it so

Yes, I agree. In this case, though, the person who "has it" is the owner. Not the person who signed a deal saying "I myself will use this under the terms we have both agreed upon" and then proceeds to break those terms. Copyright law (in the US) is bullshit and needs a whole lot of reform, but if we're talking about media made recently? By a still living human? Yes, they should own what they create.

but many pirates are productive members of society or couldn't buy to begin with

Yes, I imagine this applies to both you and I as pirates. But as a productive member of society, I am fully aware that I am not entitled to anything owned by anyone else. I will not die if I don't see that new movie I want to, and I am aware of that. I know that me pirating is both immoral and illegal, and directly hurts others. I am willing to admit that.
