So basically unless you've made FP+ reservations you should just go to Universal where you can get express passes that day for a fee. Better yet, since there's no incentive to stay WDW onsite now, you can stay onsite at Universal and get Express Pass Plus free which is far superior to FP+ and them just show up at WDW parks on the days that seem optimal for whatever FPs you were lucky to get or do rope drops and squeeze in your rides before lines start then go back to Universal to do FOTL.
You are taking my reference to Universal too literally, but essentially, you are still correct.
There is a LOT to do in Orlando. A couple Disney execs have openly said that the entire point of FP+ is to get people to "lock in" days to Disney. That once people have picked out their FP+s, they are far less likely to do other things Orlando has to offer, this also bring them and their spending money for that day on to Disney property. All good things for Disney. That's the point of pre-booking, straight from the horse's mouth.
If someone goes online to book their FP+s and can't get what they were looking for, it sends a lot of negative messages, the potential to not be able to ride that ride (though in reality there would be stand by, although, again, maybe they don't want to wait 2 hours), it may indicate that WDW is "too busy" that day, it might just seem like their ticket wouldn't be worth as much because they were unable to get their FPs.
This in turn, makes doing other things in the Orland area more attractive by comparison. Disney does not want people to show up at the gates and buy tickets, it wants them to pre-purchase their tickets and "lock in" days at WDW. That really is one of the major purposes of the system, that and crowd management.
