(FYI, I'm not arguing that people should be banned for spawn camping, only that it should be discouraged because it is petty and often serves no real purpose.)
Money is a bonus here. Stage advance is probably the best reason to feed on an badly placed spawn.
Stage advancement is not necessary to win, especially when your opponent really screwed up.
Besides, if it wasn't for the risk of spawn killing, the only penalty for a badly placed egg would be that you have to rebuild it somewhere else.
Even ignoring "glitched eggs" and spawn camping, there are plenty of penalties for badly placed spawns.
Mistakes made by the players need punishement.
How very righteous of you.
Actually no, punishment is not needed for making mistakes. Hopefully, people can learn from mistakes instead of being harassed every time they make one.
You say "the goal isn't to make people miserable" but then you say that mistakes should be
punished.
You also said "If experimenting means [failing badly], then by all means don't do it while I'm in the same team as you". Since the whole purpose of experimentation is to find out what does and does not work, this means you never want anyone on your team to try anything new.
You take the game way too seriously.
Only inexperienced aliens complain about spawn camping
Actually I've heard plenty of experienced players, humans and aliens, complain about it. I don't bother. If the game doesn't seem like it's going to end soon and the other team is compulsed to spawn camp, I usually find a different server.
