I strongly disagree that the way to improve support for mums to be able to breastfeed is adding more guilt, shame or expectation.
If the aim is actually support, then wouldnt this thread be about looking at practical solutions rather than sharing information suggesting breastmilk is preferable to formula? So maybe campaign to improve access to lactation consultants being more common on NHS, or improve midwife training about breastfeeding, or improve NHS care in hospitals after labour generally so women are helped to physically recover when they're being expected to learn how to breastfeed, or improve maternity pay so after 6 weeks they're not debating how long they can cope without a decent wage, or whatever.
I'm breastfeeding my son. The experience has only made me more grateful that formula exists. It was a tough (at times) journey to get feeding established even with plenty of factors that "should" have meant I found it easy.
