That's maybe the second law. The first one is: money is always finite.
Look at how Elon Musk behaved. Do you think VC gladly approved what he did with Twitter? They might want to keep chasing quarterly results - but sometimes, like with Zukerberg, they can't. Not enough money. Similar examples with Google rounds or how much more financially backed politician loses rather often to a competitor. Or, if you will, Vladimir Putin's idea that he can buy whatever results he wants - and that guy is a very wealthy person. There are always limits, putting the money law to the second place. We might argue that often the existing money is enough... but in more geopolitical, continuum-curving cases there are other powerful forces.
The Twitter acquisition wasn't funded by venture capital, so your question about VC approval doesn't apply.
If you're using VC as a general term for "investor" (inaccurately), then the answer to your question is that the major investors, such as Larry Ellison and the Saudi monarchy, wanted political control of Twitter, which meant that they did (apparently) approve what Musk did with it.
