Detection of viral RNA does not necessarily indicate the presence of infectious virus.
To me, the important bit was in the source report

Among 3,711 Diamond Princess passengers and crew, 712 (19.2%) had positive test results for SARS-CoV-2 (Figure 1). Of these, 331 (46.5%) were asymptomatic at the time of testing. Among 381 symptomatic patients, 37 (9.7%) required intensive care, and nine (1.3%) died.

This shows it doesn’t matter if "you feel fine" - nearly 10% of the passengers on the Diamond Princess didn’t show symptoms at the time of testing, even though they were infected (thus able to infect others).
