Yes, I think it is greedy to have people pay full price for something that is essential a alpha/beta, even if they call it early access.
Crowdfunded games have you pay MORE for early access.
Here is the thing: if you are not sure if you won't to buy Baldur's Gate3 - then don't buy it yet. Larian doesn't want to encourage people to buy in early, if they are not already interested in BG3 - they have been vocal about it, and pricing supports it. You have nothing to gain by buying to EA - you will get the worse experience and you pay the same as if you wait. If you are interested in BG3, however, and want to provide feedback and be a Guinea Pig for their experiments - you can pre-order the game and test it. If you are not interested in it - wait for 1.0.
EDIT. As mentioned before, there are titles that release for full price in EA. It is uncommon, and generally business model wants people to buy in early (aka. we need money to actually work on the game). Not so much in this case (Can't speak about Larian's budget but 1) with that scale it would be silly to count on EA money to finish the project 2) they said it: Buy EA only if you want to make the game better.
