(then again, I also find it worth learning how things are done in other countries, so I believe both the Durants' statement and your proposed riposte may be true at the same time)
[as for the truth: from a DBMS' WAL (the past) one may always reconstruct its tables, but for queries it's more convenient to always have them materialised (the present); does that make sense?]
For whatever it might be worth, I'd also tend to agree - they are not incompatible notions ...
