The practicalities might need some work, but I am generally in favour of an approach like this. We should make sure those people paying very high prices get priority for seats, ahead of those on cheap tickets. Let's not go down the budget airline route of penalising the most profitable customers!
But you aren't paying the premium for the seat, you're paying the premium for the versatility of the ticket. Thinking of Standard Class, you've got:
Anytime, Any Permitted - any train, on any route, at any time between the two stations mentioned on the ticket, with no restrictions on break of journey;
Anytime, Route/Operator specified/restricted - any train along or avoiding a specified route or operator, at any time of day, with no restrictions on break of journey;
Off Peak, Any Permitted. Restricted time, but any train during those times, with restrictions on break of journey;
Off Peak, Route/Operator specified/restricted;
Super Off-Peak, even more restricted validity;
(And of course, these can be bought on the day of departure, can be amended for only a handling fee, or cancelled if booked in advance and mostly refunded. And all of them can come with a reservation if required)
And bottom of the heap is the Advance, which is entirely restricted in terms of route, time, train and seat, and if you're going to get one of these "cheap" advances you even have to commit to the exact journey that you wish to take 12 weeks in advance. With no possibility refunding if your plans change.
And it's the total absence of flexibility that requires the purchaser of the Advance fare to have a reservation, because if they can't get on that train, they can't make the journey that they've paid for.
