A lot of this is why I now find the US/IoA experience far superior to WDW. You stay on site there, you get the express pass included. You save hours of time, just as a bonus of staying on site in a lovely hotel, for half of the cost of a Disney Deluxe. If you don't stay on site, you pay $50-$125 a day for the privilege. I actually don't think that is unreasonable. At least it gives everyone a fighting chance, if you are willing to fork over the dough.
I realize the same system would never work at WDW due to the sheer number of rooms on property, BUT, (and I realize I'm in the flaming minority), I'd pay $100 a day extra to have an
every ride fastpass, able to use all day long. I'd do it in a heartbeat, with a smile on my face. I think standing in more than two 120 minute queues per day may make a lot of people run to guest services to upgrade to never do that again, if given the choice. Especially 1st timers. I'd MUCH rather have a pay system, with more ride availability, than this tiered system with limited selection.
We already doll out $5-7000 total for a Disney vacation, an extra $500 for fastpass privileges is nothing, really.
And, like the OP says, no one would HAVE to use it.
