If something has only existed for decades it is essentially brand new and in a trial period, the trial failed. The context Chesterton meant was for things that have centuries or millennia of history behind them being upended. I'm sorry I know we like to feel very important in tech but if something hasn't been a thing for 100 years it does not matter historically.
There is no mystery why these institutions that are 30 years old exist, we have the documents and probably the people that formed them still around. We know what they got paid for and what they did.
It's a very different thing if we have some cultural historical tradition (say gender roles, alcohol, only males voting, the stuff Chesterton actually talked that were actually issues at the time) that has persisted for centuries or thousands of years being upended because "i don't like it" without understanding it's actual structure.
Here's another good quote (the book is free to read, quotes are no way for actual human beings to think https://www.gutenberg.org/cache/epub/470/pg470-images.html#c... )
>Suppose that a great commotion arises in the street about something, let us say a lamp-post, which many influential persons desire to pull down. A grey-clad monk, who is the spirit of the Middle Ages, is approached upon the matter, and begins to say, in the arid manner of the Schoolmen, “Let us first of all consider, my brethren, the value of Light. If Light be in itself good—” At this point he is somewhat excusably knocked down. All the people make a rush for the lamp-post, the lamp-post is down in ten minutes, and they go about congratulating each other on their unmediaeval practicality. But as things go on they do not work out so easily. Some people have pulled the lamp-post down because they wanted the electric light; some because they wanted old iron; some because they wanted darkness, because their deeds were evil. Some thought it not enough of a lamp-post, some too much; some acted because they wanted to smash municipal machinery; some because they wanted to smash something. And there is war in the night, no man knowing whom he strikes. So, gradually and inevitably, to-day, to-morrow, or the next day, there comes back the conviction that the monk was right after all, and that all depends on what is the philosophy of Light. Only what we might have discussed under the gas-lamp, we now must discuss in the dark.
And before people think "Oh yeah this applies to USAID" this is specifically in the context of people upending historically common beliefs Chesterton viewed himself as a great defender of. If you don't think morality and truthe are real and goodness is a part of nature you are still living in violation of that and that's probably why you have a hard time understanding why people are against things like USAID. Chesterton would be disgusted to be used in such a manner.
