I think the main reason why people is still buying xrp is because they know that XRP will win the lawsuit against the SEC and they see a very huge opportunity that XRP will do to their lives.
Not only that, but this XRP token has also been in a good position in the crypto rankings before it ran into trouble with the SEC, so it's not just for the reasons you say, but there are also a few other reasons it could get people starting to believe in XRP again at this point.
