 Many but not all of the purported disadvantages of NFU as a working foundation for mathematics reduce to complaints by mathematicians used to working in ZFC that “this is not what we are used to”. The fact that there are fewer singletons than objects (in spite of an obvious external one to one correspondence) takes getting used to. In otherwise familiar constructions, one sometimes has to make technical use of the singleton map or \(T\) operations to adjust types to get stratification. This author can testify that it is perfectly possible to develop good intuition for NFU and work effectively with stratified comprehension; part of this but not all of it is a good familiarity with how things are done in TST, as one also has to develop a feel for how to use principles that subvert stratification.
