Agreed. But sometimes, especially if you know about your problem domain, it feels like asking "how do a I keep water out of my basement" and all the answers are "simply rebuild your house at the top of the hill."
It's a matter of vastly different costs, in that case: the solution to the modified problem costs much more to solve than the originally stated problem. The trick is avoiding such a large gap, hopefully with a breakeven that comes in the foreseeable future, if not immediately.
For example: how do I repair water damage on my ceiling in a way that's quick enough to do it after every storm? You mean how do I repair my roof so I only have to repair the ceiling one more time? It's more upfront cost to do both now, but the breakeven is only a small handful of storms away, which is palatable enough to get serious consideration. If the breakeven was (for some reason, hypothetically) 20 years away, actually figuring out how to make quick work of repeated ceiling repairs might be more desirable.
