They buy a large plot of land near the coastline, build condos on the far land side of it, and sell the condos advertising "bay views". Once the first block is sold out, they build the next one in front of it closer to the coastline, and sell more "bay views".
It's crazy how they can get away with advertising the view even if construction on a building that will block the view has already started.
You mean, you need somebody else to tell you if you're sold "view" today, it does not include guarantee nobody will ever build anything on the land between you and the "view" ever, just because otherwise you'd feel bad? You can not figure this out just from knowing you only own property rights on the small piece of land and not on anything else, and did not buy any "view" rights? Maybe if you can not figure this out, buying expensive property is not the best way to go for you, at least without consulting somebody knowledgeable in these matters. You can not expect everybody behaves in your best interest, and they certainly do not owe that to you. If you don't own the rights and the land, there's zero guarantee the view will be there tomorrow.
Of course I can figure out the misleading advertising from property developers, it's common knowledge and has been going on for decades. If I become interested in buying a place one day, I'll look up planning permissions around the area and judge the risk of the neighbourhood changing.
But that doesn't mean that we should accept or approve misleading advertising.
It's not even a case of "who knows what might happen here in the future" - they keep advertising the views when they themselves are building in front of it, and the basement has already been poured.
