Think even bigger, why not reinvent the wheel every time every product is developed? Why have a common platform for anything?

If you think about it, what value is there in all these companies using the same roads to ship products? Can't they build their own? And is it really important that every business accept the same currency?

Yes, platform independence and shared universal access to common standards that consumers can consistently trust to provide similar experiences across products and ecosystems does admittedly reduce wasted development resources, increase competition, and makes the market more accessible to new businesses. And sure, I guess technically it reduces consumer confusion, and sure it benefits consumers by making products and services more interoperable. But who are we to say that any of that is good? /s
