You will see numbers thrown about that with gigabyte blocks a node will cost roughly $20000 a month to run this is out of the budget for most businesses so you will only get large corporations and the miners running them

While this is generally ok you are putting complete trust into a few all the BCH mining pools are "friends" so if they decide for instance that the low fees are not enough to sustain a profitable business they can just increase the coin supply as no one else can afford to run nodes you just get forced to accept any changes or move to something else.
