The point is that you’re not fixing the problem, you’re just masking it (and one could even argue enabling it).
The same way adding another 4 lane highway doesn’t fix traffic long term (increasing highway throughput leads to more people leads to more cars leads to congestion all over again) simply adding more RAM is only a temporary solution.
Developers use the excuse of people having access to more RAM as justification to produce more and more bloated software. In 5 years you’ll likely struggle even with 32GiB, because everything uses more.
That’s not sustainable, and it’s not necessary.
