This is what was being done to some extent in Australia by isolating old peoples homes. However most of these facilities are privately run, and are staffed with low paid workers on part time casual contracts to maximise profits. The workers therefore need second and third jobs usually at more than one of these facilities and still with plently of contact with the rest of the community. When the workers get sick with covid themselves thet cannot afford to isolate as they would be sacked and replaced, so they continue to work and infect all the facilities that they work at.
