A quick summary for the English-only speakers.
Aztekior defended the right to trash. His own experience was that at the beginning of some event he abandoned his non-event plants and then picked up some seeds from the wild garden One of those was bred and so he trashed it - there is no limitless abandoning and he did not want a bred variant so he did not have much choice. He even considers the breeding and abandoning of event plants rude and thoughtless, when it is done at the beginning of an event period. If he could not trash he would be forced to play the way others want hom to instead of his own way.
I see what he's saying here. Yes, I agree with him; I don't like it when people breed event plants at the beginning of the event, either. At that point I prefer parentless, and if I got a bred one I would be a bit annoyed. I only breed event plants at the END of the event, when the wild ones will no longer be generated, so anyone who wants an event plant will need to take a bred one. At that point, a player can't be picky; if he/she still wants an event plant, the player has to take what he gets.
Others have reminded him that he connot tell the rest of the players how to play just so his own needs are fit perfectly and so he would just have to live with getting an abandoned plant now and then as well as others will have to live with their seed being trashed.
That is true too. I am always a bit saddened when an event seed that I bred for the wild in order to be NICE to other people gets trashed, particularly if it's an event plant that can ONLY be gotten bred. (Such as the christmas stars.) I've had some of my released Christmas Stars get trashed before, and I was a bit peeved; if someone was going to trash it, why even pick it up? Was the person just wanting to prevent someone else from getting it? Why not gift it on the gifting thread instead of trashing it, if you don't have the abandon option? It was an EVENT plant, after all! So you can see why someone who is trying to do others a favor can get a little upset at someone else trashing the plant, no?
Basically Aztekior supports a nursery as it allows different playing styles without much interference. As an alternative he suggets a mouse-over function wher you can tell what plant you'll get before picking it up. Urusta described a way to do this very thing within the existing system (get plant number, copy into another plant's page) but Aztekior condemns that as too complicated.
I know about Urusta's method, but I've never used it, because I agree with Aztekior; it's too complicated to want to do for every seed.
A thing worth translating however ist Nephele's post:
"What I don't get is: the game does not make any distinction between bred and parentless seeds, the only difference being that some have a family tree to look at and others haven't. It should, therefore, not matter if the seed you pick up is bred or parentless. If anything, the bred variant should be more desirable as ist is, in several instances, the only way to get a specific variant."
It's just a matter of preference. To some it doesn't matter, but to others it does. To me it doesn't really matter so much, but I've seen many people who want a plant with "parentless parents", or which is parentless itself. I generally PREFER parentless; it just feels more that the plant is mine, without any interference from anyone else.
On the other hand, it's kind of fun to have a plant with a "history" as well. Wasn't there one plant being gifted around from one person to another, to specifically have a really long gifting history?
I personally don't need a nursery as I dont mind long plant histories and like a plant with a nice family treed as a surprise from the wild garden. If I wanted to avoid that at all costs I'd use Urusta's method as I realize that trashing might offend the breeder.
Honestly, if there was a nursery as well, most people will probably use the wild garden, and be glad that they don't have to worry about the parented seeds. So in a way it's a way to get rid of seeds from the garden permanently, which is a little sad, but better than them getting trashed. On the other hand, it's also a way for people to know where to look for the event seeds that others breed and deliberately abandon for people, when they are unable to find them in the wild. Also this way people won't end up trashing the "bred only" varieties that they see in the wild, not REALIZING that they are breed only variants. And... for those who DO like a history (which sometimes I do), it's a place to go to find seeds that DO have a history to them.
