It's anything but clear although I think a self-appointed group assures us they know what's best despite tolls being wildly unpopular when real people are asked.
"If presidents could be prosecuted for their official acts"
This has always been presumed to be the case yet it has never resulted in what you say. It's a nonsense theoretical as cover for what is otherwise utterly indefensible as making the president king.
We absolutely should price reusable bags higher then.
If I forget my bags and I don't have many groceries I'll just not use bags at all. Otherwise I'll use paper, which isn't great but it's not adding to plastic trash.
Also plastic bags are generally around a $1. I'm not throwing those away, economic reasons and on principle.
We should be making much more low end housing, absolutely. That said, even the cheapest housing costs the time of tradesmen and substantial materials costs, not to mention land. It will always be a substantial chunk of minimum wage earners' income because minimum wage is too low and/or out of whack with real costs.
