Pretty much all these arguments boil down to "yeah, but Bitcoin wouldn't be worth as much if X happened". I don't think you'd find anyone to disagree with you.

Pretty much all these arguments boil down to "yeah, but Bitcoin wouldn't be worth as much if X happened". I don't think you'd find anyone to disagree with you. There are absolutely drawbacks and tradeoffs. If Bitcoin becomes banned/regulated by a significant number of countries it will still perform exactly as it is doing so today in those conditions. It just might be "worth" 1/100th of what it is today. If you take "price speculation" out of the picture, I think your rebuttals here are entirely invalidated.
