No, the modern ideas are fine for what they are. You can disagree with them if you want, but they are just ideas and for many people they are good.
The problem is we are setting government policy based on a one-size fits all idea of expectations and those who don't want those are forced to either follow anyway or live a worse life in other ways for not.
yes thats how society works, you give up certain freedoms for structure, safety, and access to resources. This idea that society should conform for lifestyles that dont support the continue existence of the society is pretty dumb
Not really, governments have been encouraging family formation because it brings up new taxpayers since, well, forever.
Which does not make single-living idea weird or dumb, ofc, but it makes it additionally expensive on top of the natural cost (just like multi-floor houses are cheaper per surface built).
