Stone or concrete walls are normal in many countries.
You can indeed use a hammer drill to drill holes. You can buy them for as little as 30 dollars these days. And you can use an angle grinder to make cutouts for cables/tubes, and apply plaster afterwards.
Many houses in the colder regions already have cavity walls with insulation in between the walls regardless of the building method, so I don’t think this method is very wasteful in amount of material.
However, I agree that 3D printing houses had various downsides, such as the weird surface, inflexibility to modify/expand/repair after the initial build and potentiality worse insulation characteristics. I am more of a believer in prefabricated houses, where building houses becomes an industry instead of a project.
More accurately, there has never been a EU law that forced people to create cookie banners.
The EU law required websites to have the users’ consent to use personal data and tracking. The law never even mentioned the word “banner” but this is what the industry chose as a solution.
Furthermore consent is not needed for functional cookies. So all websites that enforce cookie banners upon users do really use tracking/data sharing or their partners (such as Google Analytics) do.
