That doesn't mean anything. Not all rabbits will bond. And it has nothing to do with "alone their entire lives" either. 3 month old rabbits who are starting to mature can still kill each other.
There is nothing wrong with rabbits living outside either.
People do what is best suited for their situation.
Numerous outdoor bunnies lead much happier lives then even some indoor bunnies.
Its not in a rabbits natural instinct to play with toys or use a litter box or live in human houses, but we still do that. And wild rabbits living in "large groups" doesn't mean their bonded either. They can often tolerate each other, but they have miles and miles of space they can be away from each other in when they encounter each other. You never see 20 plus rabbits together all grooming each other. They live close to each other because that's just what rabbits do, breed and eat and try and survive. And just because 2 rabbits mate, does not mean their bonded either. When I see wild rabbit colonies here, there never in pairs, their only close together because they will be killed if they wander any further away from the safe spots. Doesn't mean their bonded or being social. Their all evenly spaced away from each other, their still territorial animals by nature.
We tweek their instincts and bond them for our own peace of mind.
People not being able to bond 2 rabbits they own does not make them lazy. It doesn't always work, end of point.
Rabbits do just fine on their own.
Rabbits do just fine outside.
Rabbits do just fine with no free time.
Everyone will have their own opinion because it works well for them. And it works well for their rabbits. If it didn't they wouldn't be doing it.
