It would be absolutely asinine to assume that a layman could understand, much less implement the currently available solutions in an effective manner, so here are the two scenarios that small businesses are faced with:
a) They still wanna make use of cookie powered tech and just do it without consent, which opens them up to legal trouble
b) They don't do it and give up on functionality, which big biz will be able to provide, putting them at a disadvantage and making the web less democratic in the process once again.
While I have no particular thoughts about the type of providers targeted here, I am certain that the last thing the current setup needs is additional complication.
