It depends on where it is used, though. Apples and oranges. You are comparing Alcantara to leather. The real comparison there would be Alcantara and Tesla's weaved cloth textile. If you made a steering wheel out of Tesla's base weaved cloth headliner material, sorry new Premium Textile, I guarantee you it would be even worse in a steering wheel after a track day.
In a headliner, Alcantara in reality is much more easy to clean than a weaved cloth. In a steering wheel any textile or suede is of course more prone to what you say than leather, but Alcantara much less so than many other synthetic materials. OTOH, Alcantara is less susceptible to scratches or slips than leather, so some may like it even in a steering wheel... (Just wash it.)
I wouldn't personally want an Alcantara steering wheel, nor on the seat base which is subject to heavy wear in a car (Alcantara can frizz from heavy wear over many years on tight surfaces that get much wear). But on doors and headliners (even B pillars, where Tesla's leather scratches oh so easily on the Model X), Alcantara is IMO much more durable and easier to clean than leather, let alone some weaved cloth...
Alcantara is one of the few materials that I've seen that actually, when washed from time to time (it is water washable!), actually looks like new for years. It is quite amazing. I have couches made of the stuff that are nearing the first decade mark and they still look brand new after a wash. Leather by now would have significant patina or likely some scratching and usual textiles would have some staining that wouldn't come off, but not Alcantara. There are literally no scratches, stains or wear after soon a decade of daily use. It doesn't look worn out either.
