It's easy enough using #1 alone, so long as you're prepared for the volatility i.e. a 50%+ drop in any year. The growth rate of the bitcoin price is still ~35% year over year. FIRE traditionally calls for a 4% safe withdrawal rate, expecting at least 7% average market returns. You could use a higher rate than that with bitcoin and still probably never deplete your savings.

Loans seem risky. Lots of these shops have gone bust in past bear markets. Also you give up your keys.

Covered calls - you could, but how much do you expect to make? Bitcoin can often surprise to the upside in short bursts, so it seems like you're giving away most of the benefit for limited profit.

Income strategy: again, you're giving up performance to dampen volatility. And you cannot hold real bitcoin.

All of these strategies outside #1 should probably make you ask why you can't make it work with a >30% annual growth rate alone. You are already playing on easy mode. I think quite a lot of bitcoiners have made it there, but you're unlikely to hear them brag about it either. Maybe we need more bragging.
