Thank you for your insight! I thought that if anyone here knew, it would be you. The domestication of a species is always an interesting conversation. I think the latest creatures that have been/are being domesticated are hedgehogs, though from the small bits I’ve read about it I don’t think it sounds ethical! But then I suppose thousands of years ago, when guinea pig domestication started (and that of other wild animals) I don’t imagine that could’ve been ethical either.
4000-1000 years before Christ (guinea pigs were domesticated around the time of the pharaohs and the first large agricultural empires like Egypt, Mesopotamis or the Indus Culture), people in the Andes were focussed on ensuring their survival in a notoriously extreme climate. Guinea pigs were farm animals providing an important source of protein in the absence of poultry, sheep, goats, pigs and other Eurasion/African domesticated farm animals.
Since South American human social cohesion used to rely on large communal feasting, in which guinea pigs played an important role, we should be VERY careful in applying our own ethical views and judgment to other times and other cultures. The continuing popularity of guinea pig meat in those countries, which is usually abhorred by pet owners elsewhere, also needs be seen on that background with VERY deep historical and religious roots - it is one the same scale that some pre-Christian traditions still survive until today within a Christian contect but still deep emptional attachment - see bonfire night and all those very ancient fire traditions in countries with prounounced winters and long nights. The Incas for instance built their empire on food storage/food distribution in times of failed crops and communal feasting on an enormous inter-tribal scale much more so than on military expansion.
Because Europeans and North Americans have only ever known guinea pigs as pets for the last 500 years and less, we completely lack this kind of emotional traditional cultural attachment while some of our own is questionable to other cultures. Judging without respect and in ignorance of the context and the complexity of the matter is always dangerous. We can fight for changes in areas we deem as ethical only in our own time. We wouldn't be here as the human species if we hadn't learn to cook food, especially meat, at some point. We have now the choice to go vegetarian or vegan, but we still owe this debt to history. It is never that easy...
As said - there are several wild species of guinea pigs in south America (a couple threatened by extinction) and then there are domesticated farm piggies (the species that have become our pets). When having the discussion about welfare and how free our domesticated piggies should live, the one word you cannot use in this discussion is 'wild' because you are not talking about just apples; you are comparing apples with pears. Research into domestic guinea pigs and their natural instincts and social interaction has only just started, so there is not a lot of it around because they have as a species gone very much under the radar. And it also has to be clearly said that you cannot return domestic guinea pigs to a wild status to give them back their life; they haven't been wild for thousands of years.
There is also a very obvious problem with the logical conclusion from the extremists' position - who can afford the kind of space and care they demand as a minimum? Should pets only become the reserve of the privileged few (to which they mostly belong)? And what happens to all the piggies that cannot find homes - should they be euthanised like a rescue in Vancouverthat is run by adherents of this position already practises because hardly anybody can fulfill their sky high requirements? Isn't robbing rescued piggies of a life not a worse betrayal than giving them a second decent life if a five star life is not to be found?
It is good that a welfare discussion happens, but welfare is always a balance act between ideal and reality and practicability. It should be one step ahead of the majority of owners but never be unattainable for most.
