I'm surprised you haven't heard it before. "As a matter of cosmic history, it has always been easier to destroy than to create," as one wise man put it.

"Burn it all down" is easy to say. You can apply it to anything, with no further thought. It's precisely what I'd call "lazy".

To avoid being lazy, you'd have to couple it with exactly what you intend to build from scratch, and ideally how you'd go about it. That's a ton of work, not just because you have to have a concrete idea, but because you have something that people can point out the flaws of. Many of whom will say, "It's terrible, burn it down."
