Start your business on the side, when it revenue is high enough to live on, make the jump. It's slower than a funded startup, but a lot less risky. Does come with a high social opportunity cost due to lack of time, however. But so does starting a startup.
If your sidehustle does well, you can even leverage it later to fund your big startup idea. Or, hell, live a good life on a lifestyle business making a few hundred thousand per year.
$150k/year revenue won't get you any headlines, but it's plenty to live on and run a solo business.
Get to $500k/year and you prob have a higher expected ROI over N years than any startup founder.
Disclaimer: my sidehustle is at the $50k/year level, but that's on 60 hours per month. If I didn't insist on living in SF, I could have a very cushy life back in Europe.
