You act like BTC is only available in the US.

People saying "inflation hedge" are at a minimum, English speakers, and secondly, are likely Americans who were concerned about the 9%+ inflation of a year or two ago.

Alternatively, maybe they're British but the great inflation affected both sides of the Atlantic. Then again, Coinbase is an American company providing American services, so I think its safe to say that this topic is American focused.

Coinbase is an American company, but operates globally. From wikipedia:

"Coinbase operates as a remote-first company and has no physical headquarters.[5] As part of its SEC filing to go public, the company reported 43 million verified users, 7,000 institutions, and 115,000 ecosystem partners in over 100 countries."

As for inflation, let me refer you to this post (and thread), a favorite of mine.

Anti-crypto people these days have to do a lot of mental gymnastics to avoid the truth that Bitcoin (now called Bitcoin Cash) has worked perfectly for over a decade with almost no downside if you just buy slowly over time and hold/spend.

Bitcoin Cash works great and has for over ten years.

Bitcoin cash isn't real Bitcoin.

Bitcoin Cash as a standalone thing has been around for a bit over six years, not over ten.
