I think the point is that the situation isn't as weird or unusual as you might have thought and is actually happening.
Thus people are questioning this, and whether it is reasonable to expect that if you go on a date with a woman that they are actually a biological woman.
To say that the law states that a Transwoman is a woman isn't good enough for a lot of people. You can make a law to state that henceforth all sheep shall be called cows, it doesn't mean that you can get a sirloin from them.
People misreprenting themselves happens all the time when online dating, that's not new. And is more an issue with age, weight or financial status than it is gender.
