Okay so I don't know if I can change your mind at all but I can give you more insight.
Reborn dolls arent regular dolls. They are hand crafted art pieces. The artists paint them by hand. They are not even close to comparable with kids dolls that only cost what $50 or less (I think when they first came out luvabella was like $50.) reborns can cost anywhere from $200 to $6k or more for high quality work.
Reborns aren't only for people that lost babies. They are becoming therapy tools for those with anxiety, depression,PTSD or even with the elderly who have Alzheimer's or dementia. I myself have two reborn dolls and I have clothes,a few blankets,a DOLL carseat and playpen, that can't be used for a real baby, a sealed baby bottle that would have to be cut for a real baby to use,a baby brush and comb set,and 3 small stuffed animals for pictures with my dolls.
My adopted mom and the rest of her family support me in my reborn doll mom-ing because I have mental health issues and they help me. Sometimes I have flashbacks and I hold my weighted baby Violet and she grounds me bringing me back to the here and now. Could I just use a weighted blanket? No because those feel suffocating to me. Everyone is different.
I'm trying to get the courage to take my babies out with me places but I'm nervous to because of people like you. I'm not hurting you or any actual baby by having less than 30 outfits, all of them bought for the purpose of being worn by my reborns, or having a sealed bottle specifically for reborns. Also I use lotion and tap water to make "fake formula bottles* in a lot of areas in the US we can't even drink our tap water with out boiling it first. And I'm not using baby lotion for the bottle I'm using just any lotion. This is what a lot of people actually do.. Also a lot of the reborn moms with actual baby furniture..it's stuff that the ADA says is not safe for actual babies anymore. Many reborn moms post on fb asking if anyone has an expired/old car seat or stroller. One that would have no other purpose anymore. As for those that have a real baby crib, some of them actually had the cribs made by family members for their reborns. So they didn't go to Walmart or any store that sells cribs and buy one from there..or they go to yard sales..but if they are at a yard sale and they see a lady who looks like they might be pregnant or they are carrying a baby and looking at a crib..they leave that crib there for that actual mom. We are not greedy. And if we do get tired of the clothes we currently have we trade with other reborn moms, or go through our current collection and decide which outfits we are totally bored and done with, donate those to goodwill, and from that same goodwill,find a few things that we like more than what we donated. So I promise we really aren't taking from real moms.
