For this manga in particular it's always best to just skip the first page of comments, it's without fail full of people whining that the characters aren't just doing things that have already been directly stated to not work and lead to even worse outcomes
There's more after your comment still low key whining about it. There will just always be some. It doesn't make much sense for me to address any of the comments tbh.
Because if the next chapter isn't more vanilla Yuri or royals laying down the absolute power people think they possess (and wish they themselves had, by the sounds of it), then there will be some morons doing it all over again.
But it helps set my mind in order to call them out anyway. Ignoring it and not articulating out what I think about such views often leads to quiet long term acceptance and atrophy of ability to scrutinize. Thinking about it internally isn't enough. At least for me.
