citam to inak a nieco je vec interpretacie, ale "tie dovody su hlavne, ak nie iba ekonomicke." proste nie je pravda.

First things first takze najhlavnejsie dovody su v prvej vete:
1) je to neefektivne
2) plytvas zdrojmi a (vyrazne) zhorsujes svoju sancu reagovat.
Proste vela sikany za mizivy vysledok je zly trade-off.

Ciastocny kontext je, ze supply chains su momentalne velky problem - https://www.who.int/news-room/detail/03-03-2020-shortage-of-personal-protective-equipment-endangering-health-workers-worldwide - a to nie je ekonomicky dovod, ale zdravotny.

No a potom tam je este toto: Countries implementing additional health measures which significantly interfere with international traffic are required to provide to WHO, within 48 hours of implementation, the public health rationale and relevant scientific information for the measures implemented. [...] Significant interference generally means refusal of entry or departure of international travellers, baggage, cargo, containers, conveyances, goods, and the like, or their delay, for more than 24 hours.
- a z mojho pohladu izolaciu (v europe) podla tychto kriterii obhajit ani nevies, lebo proste uplne nulovy pohyb mat nebudes.
