Couple of observations - if you haven't already, I highly recommend some options education before getting into them and trying them out. My best and easy education source are the education videos from
Option Alpha. Figure on 20-30 hours to go through all of them. They're arranged in 3 blocks that I think of as 1) intro, 2) getting into a trade, and 3) getting out of a trade.
That's not the end of the education, but it's a good start.
The other observation is that I do share your long term (by 2030) view of TSLA's up side. But also remember that with even deep ITM call purchases, then there are two things that become true that aren't otherwise true from owning shares:
1) leverage on the way up, is also leverage on the way down (unrealized gains and losses are accelerated over owning shares)
2) the position has time value that decays. There is always more risk simply owning options as a replacement to owning shares. Going deep ITM is a good mitigator for that. But you're still on the clock now where you're not with share ownership, and the market can be irrational far longer than you (any of us) can remain solvent. Yes - you can also mitigate that time decay by closing or moving out positions that are down to 6-12 months or so (whatever works for you).
Easy example from TSLA's recent history about sideways trading, when the expectation was strongly up; the roughly 5 years of sideways trading, where just about everybody here agreed with the observation that the spring was getting wound tighter and tighter, and the shares were underpriced. I thought a breakout after 2 or 3 years was imminently reasonable.
I'm not saying don't do options because they're dangerous - I'm doing quite a lot with options these days. But do remember that every choice has risks and rewards, costs and benefits. If you can't identify the tradeoffs in any investment decision, then that's a good hint that you shouldn't do it (learn more - ask questions!).
A good way to find those limits is to do some boundary testing - what happens if the share price goes down 50% (I consider this inevitable at least once between now and 2030) and what happens if the share price doubles (both in a short timeframe - say 1 month). Or what if it was even worse - 80% down over 3 months; 3x in 2 months (depending on the position, up 3x can be a bad outcome).
