This.
I've seen a lot of confusion in this and other threads over the logistics of how Disney could possibly implement this. I don't see why it has to be complicated, even with multi-day tickets. They can do exactly the same thing they've already done with the annual passes. You buy a ticket at a particular level; aside from the highest level, which would presumably be unrestricted, your ticket has certain dates blacked out. You can't use that ticket to visit on those dates. If you are planning a 10 day trip, and 9 of your days are included in the "Bronze" ticket but one is blacked out, then you either upgrade to a Silver ticket (or even Gold, depending on the dates), or you don't visit the parks on that one day.
For example, due to the unfortunate placement of Easter this year, the last couple of days of our March Break trip overlaps the premium Easter dates. I considered picking up a DVC Gold annual pass for this trip, but I wouldn't be able to use it on those last couple of days. I'd have to buy a Platinum pass, and that's not worth the cost. So I'll stick with my 7-day base ticket, which for now will get me into the parks on all days of our trip. If the base tickets were tiered with the same dates as the APs, we would have had to decide whether it was worth it for us to pay the additional cost for tickets that covered the premium dates, or whether we would buy a shorter ticket and just skip the parks on those days. Or change our dates, which wasn't really an option for us.
Nobody has to like it, and it might not be what Disney is actually planning. But unless I'm overlooking some complication here, it's not logistically difficult, or even particularly confusing.
