This is victim blaming. Being aware of everything will paralyze you to inaction because you can't read a 20 page TOS just to view a website or buy a hairdryer. Like so many things in our society right now, this is a trust thing. Functioning societies have a level of trust that allows greater return than the maximum minimum. If I trusted companies more I would buy more things. But I don't so I avoid things like new cars and 'smart' TVs. That trust is generally built up with strong institutions and things like 'consumer protections'. Right now however people believe in ideas like 'buyer beware' and 'it is the buyer's fault for getting scammed' and it just leads to a weak economy filled with junk that people hate but have no other option.
This confuses blame with being deserving. Do victims deserve what happens to them? No, generally not. Someone who is attacked and assaulted in a dark alley at 2:00 in the morning does not deserve that, the perpetrator would be to blame for that. But could the person have avoided it by not being there at at that time? Yes, at least in many cases.
Thinking one can skip down the trail of life without having to watch out for wolves is just being naive. Most of us lock our doors at night.
I have lived in places where you needed three keys to three different doors to get to your apartment and everywhere had bars on all the windows and I have lived in places where you could leave your bike unlocked at your front door and not worry about it missing the next day. I'd rather live in the later and it is possible to have that life.
I've seen this arrangement countless times in cities:
First key for the gate on the road to get into the yard.
Second key for the gate in the yard to the stairs and elevator.
Third and possibly fourth key for the door to the apartment.
That's pretty normal. I've seen at least once another key for a door between stairs/elevator and the home door. That's because of many burglars in the very first months after the building was built.
That said, I agree with you that living in a place where you only have one key and nothing happens if you forget to lock the door is much better.
