You only "need" to upgrade your deck if you want to play competitively. The vast majority of Magic players (according to Wizards' own research) play casually with no format restrictions.

On top of that, Wizards supports Modern, which is non-rotating, and (to a lesser degree, because of the reserve list) support Legacy and Vintage as well.

If you want to draft without dumping money into it, there's Cube.

There's a million different ways to play Magic, and only some of them have the "problem" you describe.

I put quotes around problem because the rotation is actually a solution to a different problem: staleness. In Modern, Melira Pod has been one of the top decks for several years. There are a group of people that do not want to play against the same deck all the time, hence rotation. Wizards does plenty to support those that want to play a non-rotating format.

I'm not an "apologist" I'm just using my knowledge of the facts (ie, Modern exists and is supported) and common sense (what's the alternative to printing more cards? just ... stopping?).
