The endless forking means it can’t be entirely centralized.
It doesn't mean it can't be centralized, it means it's either sentenced to die from diffusion or it becomes centralized by default. This is why metals are better, you can't make a new gold or silver in your basement then log on bitcointalk and say "I JUST INVENTED ANONYMINT GOLD, BUY THIS SHIT FROM ME STUPID GOYIM", while a million other people do the exact same thing. Instead of incentive for consensus, there is incentive to diverge from a single chain, an inverse Schelling point if you will. There is no financial incentive to diverge in metals because the number of noble metals is finite and can't just be invented ad infinitum.
Even if there was no incentive to create new chains in a get rich quick scheme by printing or cornering the supply yourself and saying "my chain is 1% better than the others, buy it", the inverse Schelling point in crypto would still remain because scaling is terrible due to the so called triple entry accounting (but it's not exactly triple entry accounting if it becomes entirely centralized now is it?). Since scaling is terrible, fees are non-trivial and usurious, so people would bunny hop from one to another infinitely to prevent having usury levied upon them, which is why many people are sending transactions with things like Litecoin right now.
The only way consensus would be achieved in crypto is by force, the pointing a gun at you and saying you're required to use so and so chain, otherwise everything dies from diffusion (which is a good thing since the noble metals are better in all aspects anyway). That is unless bitcoin forever remains some type of small, niche, regulatory arbitrage product for a few people to buy drugs on an internet site. In that case, the internet site itself is forcing consensus by saying they will only accept so and so cryptocurrency. Unless all 1st world govts collapse to shambles, regulatory arbitrage in this manner will be crushed for cryptocurrency if they maintain anything resembling current power levels, though. Instead of the internet drug site forcing consensus on a cryptocurrency, it will be the govt.
Eating granola that looks like this. I'm guessing it tastes better and has more nutritional benefits than women's diet crackers.
