These days, I've been watching people argue about whether the pledge and shared security are just "nested dolls." I keep thinking of options: the buyer pays rent every day, and the time value slowly leaks away like water; the seller seems to be collecting rent, but in reality, they're using tail risk as collateral. Usually, it's quite comfortable, but if something really goes wrong, they might vomit everything back up all at once. To put it simply, who is the time value really eating? Most of the time, it's the buyer's patience being consumed; occasionally, it's the seller's sleep being taken. I'm now more inclined to keep things simple—if you really want to gamble, treat your position like a flowerpot, water it if you like, but don't put the house on the line.
