Help with understand covered call ETF's as income generators, or better alternatives?

As I understand it, covered call ETF's:
Generate monthly ordinary income at better rates than high yield bonds. Ordinary income might be a tax drag for some people though.
The trade off is significantly reduced growth.
Volatility risks still apply significantly, but are reduced to some degree vs. a standard ETF.

The last point is seemingly a hot debate point for a lot of people, risk averse investors will tune out everything else and beat you over the head with that point. I want to better understand their concerns because they seem very attractive to me as an aggressive income generator, if I'm willing to accept volatility risk, hold through dips and just keep buying more.
Are there safer alternatives with similar yields?

For context, background, TLDR etc.
I have no realistic opportunity to increase my investing contributions through meaningfully increased wages, hours, or a second job right now or in the next few years. After maxing out my roth contributions, I don't have much left to save or invest without completely going no-life and living like a monk who eats, sleeps, exercises outside, works, and devotes his life to growing a brokerage account. I've been doing it for two years straight, it's becoming detrimental to my well being to push any harder to save/invest any more of my actively earned income. I can't pick up enough momentum through active income to be satisfied with my contribution levels anymore. They won't compound fast enough to increase the quality of my life until the far future. I need to start building a passive income generator for the grey area between now and retirement, and it needs to be more aggressive than just hoarding bond funds, which I'm also accumulating.

My hobbies are down to exercise, books, time outside, etc. I don't date or spend money on socializing. My friends are minimalist hikers and campers and mountain climbers, our activities are cheap and healthy. I've hit a hard wall in terms of what I can squeeze out of my labor and time. It's a real wall, not "lifestyle creep" that basic advice about cutting expenses will resolve. My lifestyle is minimal and if I lowered my standards any further I'd be living like a prisoner
who's doing 20 to life in a work camp somewhere but has a stash somewhere once he gets out.

I'm at a breaking point where I need to aggressively generate passive income with smaller amounts of leftover cash if I'm ever going to gain momentum. I'm willing to take on some volatility and risk for sake of meaningful passive income paid monthly, even if it's taxed as ordinary income for now.
