I read your post several times and still have difficulty following your argument. And it is not an issue with English skills on my side.

Most legacy carriers in Europe and several in Asia permit one carryon plus one personal item. There may be restrictions on weight, but one is still permitted to carry two pieces on board in most of the world. The differences however are enforcement of the rules, generally quicker checked baggage retrieval, and fewer checked bag fees.

And many of us here who feel strongly about balancing risk have lost friends and family in terrorist acts or under totalitarian regimes in past. We don't however use that as an excuse to give up rights and freedoms.
