I do agree it is possible. I could very well write an article for 5 reasons you should use Magento; there are already a lot of those. To make the right choice you need to know as much as you can. I think Magento is still today okay for SMB’s as well, it all depends on what is the priorities. For scaling well there is a list of issues. File storage has no abstraction(if you have terabytes of images & videos). Native CSV import & exports can’t import 10M products (recommended PHP configuration). When you have a lot of locales the native build will take an eternity, visitor logs & a few other tables have no native cleanup system… These issues have all solutions, so it is possible. Nothing is impossible if you put enough time into it. My main point is that at the moment Magento is neither well suited for SMB’s, as it used to be; neither it is well suited for big companies. It looks like they are trying hard to be more attractive for big companies making the solution less suitable for SMB’s, while still not solving basic issues. (Paypal double orders). For alternatives, I did work on a few full custom projects. One, particularly for a big group and it, went very well. Sylius also does a good job at being very flexible.
