The government and banks will rip you off through inflation.
You can use debt to benefit from inflation, but it also carry its risks.
Ray Dalios series on the topic of capitalism being funded by debt is quite approachable.

The tl;dr is that humanity has at least an 80,000 year history of goods which are fungible, collectible, portable, scarce, and made to an exact standard, traded between people who may not speak the same language for any other sort of trade good.

Debt is where state money comes from. But shell and hunk money is where states got it from, and the systems coexisted into the late 19th century.
And so the banker is like, but of course Mr Rich Dude here's a line of credit for that 50M at a low low rate of 2% since we have so much money to lend and you can keep making the now 8% interest profits by having your cake and eating it too. And if you're 200M account starts to dip too low that you might be at risk of not being able to pay us back you can always line up some more collateral or we'll margin call and collect that 50M you owe us.
Now sorry I got a bit long winded but that's really the gist of what happens, so yes indirectly VCs are largely funded by debt.

It all becomes a vicious cycle.
