That idea seems to be ignoring the fact that other brands just haven't made EVs yet. People want Telsas now because, for a long time, they were the only good EVs on the market. As other companies are now rolling out their first EVs, Tesla's market cap will surly go down.

I've also heard the argument that Tesla's network of chargers brings more value, but...there will also be more competitors in that space in the near future (and today).

So, it seems shortsighted to believe that "market cap" is going to remain as high as it is today.
