This is a really bizare argument for anyone who actually knows about options and trades them. If your thesis is that RAM is in a massive bubble and Micron is going to crash when it bursts, you don't express that thesis by buying a put struck around Micron's current bubble price. The fact that you chose a $1000 strike as your example is weird because that's basically the most expensive way to make the argument you're supposedly making.

"IV crush" is an especially strange objection in this context. IV crush matters when you buy options at elevated implied volatility and that volatility collapses. If Micron suddenly drops hundreds of dollars because the alleged bubble is bursting then the implied volatility would sharply rise, which makes your put more valuable, not less. Invoking "IV crush" here mostly makes it sound like you've heard the terminology without thinking through how it actually applies to the scenario you're describing.

If you genuinely think Micron is going to collapse sometime over the next two or three years because this entire RAM shortage is an overhyped bubble, then the obvious trade is to buy puts around where you think the stock should return to once that bubble disappears. Micron wasn't remotely a $1000 stock before this run. We can be generous and use a $300 strike since even though that's still 100% higher than Micron's price prior to this run-up, it gets the point across.

A long dated $300 put is currently around $7 per share, so one contract costs roughly $700. If Micron eventually falls to $200, that contract is worth $10000 at expiry. At $100, it's worth $20000. If the crash happens well before expiry, it can be worth even more than its intrinsic value because there's still time value left.

If you're claiming to be certain that a gigantic bubble is going to burst and wipe hundreds of dollars off the stock price, there are long dated far out of the money puts specifically capable of expressing that position. Pointing at an expensive $1000 strike put and saying "look, options are complicated" is just a weird or rather superficial misunderstanding of some financial concepts.

I personally use options for hedging, which I think is generally the responsible purpose of them.

It's true that you can get something like a directional bet by going far enough out of the money with strong enough conviction never to exit the position early. But this also exposes you to a lot of risk that it might not pay off even though the original idea was correct. Microsoft crashed in 2000, but it never returned to its pre-1998 price, because there was some real value in the dotcom bubble and they were able to capture a disproportionate fraction of it.

None of that helps you get memory now. You're not going to see your payoff for 2-3 years or whenever the bubble bursts. At which point the bubble has burst and you can simply buy ram at a normal price again. And the thesis of this discussion is that we can't buy memory at a reasonable price now, not 3 years from now.

This isn't an abstract discussion about the usefulness of options trading or other hedging strategies. You want to pay for ram today by betting on returns years in the future? Risky play! Hope you can stay solvent.
