May be somewhat of a philosophical argument if you are limiting it to viewing the content of packets. However, there is still a ton of data that can be leaked that could be considered sensitive - volume of transactions, where they are routing from/to, the frequency distribution of that volume. Also, there is also the possibility for manipulation of transmissions - blocking/dropping them altogether causing service outages/censorship, delay/deprioritization that could affect markets, etc. At the nation-state level, this provides a lot of useful opportunities for bad actors.
