Another option is to use quasi-amorphous ($\aleph_1$-amorphous) sets, i.e. every subset is countable or co-countable. It is consistent that there is a linearly ordered $\aleph_1$-amorphous set, and in such linear order when cutting at a particular point we have that below it there are only countably many (if not, inverse the order of course). | |
