Does it make sense to use a CMS for business card sites and landing pages?

Question

CMS

While working on the frontend, I thought about this question.
Does it make sense to pull the template on the CMS, so that later it would lie stupidly. Well, maybe once every 2-3 months, add or change something on the site?
Today there are so many amazing, responsive, interactive and killer templates that are much easier to create without the hassle of CMS. And there are fewer problems with viruses. No SQL injections are scary.
From experience, it's easier for me to change something in the template than to move the entire component from the CMS.
In general, the question is of interest in which cases it is better to do without CMS, and when with it.

Answer 1

If the changes that will be made on the site are really minor. It is easier to do without a CMS, but to sign a client for technical support. And once every six months to correct a couple of paragraphs and get money.

Answer 2

If CMS bothers you - no, it even helps me for landings - it collects and minifies statics, determines the architecture, contains the necessary (and patched if necessary) libraries like jQuery, UIkit and much more, well, when it grows into a site - it’s also not a problem add page.
Convenient - use, no - no.
