Tesla’s do come with a key, it’s a card that you’re supposed to carry with you and it always works.

The phone app is a convenience feature. Although it works flawlessly 99% of the time, you should not rely solely on it

IIRC the card is still electronics which means that it will not work if there is no power or a failure in the electronics

If your electric car doesn't have any power then you have bigger problems than not being able to get inside it.

Such as? Car is enclosed so I shall not die of exposure in there by the time help arrives. I shall die outside when it is minus 30 Celsius and windy

Depends on what your problem is.

Same with any modern car with a keyfob.. Hello?

Most fobs include a physical key. I can tell you Corvette and BMW 3 series do

Only to open the driver side door. You still need the fob in close proximity at a designated spot to start the car. With Tesla cars there's no need for a physical key both for unlocking and starting.

So much ignorance in this post. You do realize Tesla engineers and designers all came fro other car manufacturers right? Even down do the audio folks who came from Bang & Olufsen.
