no, that is a terrible idea, and it is about scale and quality of life. First, there just is not the technology to do what you propose on Mars. The tech we have is limited to a few at absolutely astronomical costs and many many unknown unknowns. Second, life in a biosphere will not be able to compare to just living out in the open with (current+100Years) of Tech, Just think how much effort goes into infrastructure for people today, roads, bridges, water supply, electricity, and now imagine having to protect every kilometer from a hostile environment. Just extremely impractical.

Sure, a very select few rich people could survive this, but it just does not scale and is a pretty shitty life. There is no cost effective way around protecting earth's biosphere so that we all can continue to live here.
