Do note that I don't claim (or think) that it's very likely for this to happen. But the comment I replied to made a strong claim: that (technologically?) BTC offers this ability. This is not just some nice property that it currently has, it's part of the "intrinsic value" of BTC. This to me sounded like a claim of "guarantee", not just a claim that "nobody banned it yet, and maybe they won't ban it in the future, either".
