I don't think multiple legal contracts are important. I do think greater flexibility in certain legal rights/allowances are. For instance, I do not believe an employer should have to modify the amount of benefits provided to a person who has more than one spouse/partner. I do believe if that person is entitled to spousal benefits than that employee should be able to allocate those resources however they chose. In other words; I have at least one partner that qualifies for me to get benefits. Now, if I personally chose to spread those benefits to several partners then that should be fine. There is no extra cost to the employer for example.
