This is a common thing happens in different countries where the government mandatory give assistance to there citizens with disability, and the sad truth is that the assistance from government is not enough.
This is the perfect time to introduce bitcoin to persons with disability by doing this they don't need to rely only on government assistance, because they are now started to earn there own money to support their needs.
people with disablity is one of the priority to help by the government so they don't need to learn how to earn in crypto currency like by having a bitcoin. Crypto currency has a many aspects to earn money from it and you need to study more about this and I don't think that person with disability can take it all to learn and it depend if what disability of a person he or she have to get involved from it.
