Less meaningful, or less represented? If you sell your foundation out beneath yourself, the entire structure might come down. No matter how valuable it is to sell that rebar out of the concrete now, or how many additions that money allows you to add on top, it is likely not a sound strategy long term.

It's the combination of the two that's dangerous.
