You're experiencing pushback because your claim is ridiculous.
This isn't Les Miserables, people aren't being convicted for stealing bread or formula milk to feed themselves or their families, it's that when people are presented with high costs of things, they will happily buy things at reduced costs from criminals. Even if they could afford them.
The massive increase in criminality when wars or costs of living crises happen isn't a consequence of poverty, it's criminals seizing the opportunity to steal and sell things because they know people will buy them.
The widespread theft of high-value items from supermarkets isn't desperate Mothers stealing formula, it's highly organised criminal gangs stealing things they know people will buy because the people they sell to don't want to pay full price. Meat, alcohol, beauty products, formula, cheese.
No-ones stealing bread, veg or pulses :) that would actually adequately feed people.
I used to work in a pub where stealing to order was a thing 25 years ago, it was across the road from a supermarket and customers who had enough money to drink would put their order in for meat, bottles of booze, etc.
This was in the years before streaming services when buying a pirate copy of an album or film was also a thing and you'd have people coming round with a bag full of CDS/DVDS. Literally no-one needed a pirate copy of anything because of poverty, it was just a quarter of the retail price so people bought it.
Same as the people who steal huge amounts of clothing from stores and sell it 50% off. Plenty of people willing to buy it who could easily go without.
