Same comment, different words. You can drop out of the rat race fine - just quit your jobs. Boom, you're out.
But whether you can live happily forever on the proceeds from selling your houses depends entirely on how you live afterwards - in other words, how much you spend and whether you learn to live happily in a new location. This is unknown because it depends on your future actions. Other people could do so easily, but other people are used to living on amount such as $60k/year for a family (1.5M x 4%... I left a bit of wiggle room for college costs and transition costs). Our forum is full of people who spent more than this, learned to spend less, and liked it, but got there by specific measurable actions. Whether you WILL take such actions yourself is a dice roll. The fact you have two separate homes doesn't make it obvious that you have active thrifty genes.
Have you done such things in the past? What are your expenses? Is tracking expenses something new for you, or do you know your current expenses in detail? If you know details, you can research costs in other areas and somewhat accurately project cost of living in Utah or Colorado or wherever your youthful dream spot is. If you don't, you probably need to exercise your growth skills in the direction of cost tracking, personal budgeting, and generally sorting out priorities. This includes getting greater insight about what makes you happy.
It sounds like you have a strong base in terms of income, and the kind of asset base that gives you options. What happens next is up to you. Self exploration and honest assessments are in order. It's time to take charge of your life and make it reflect your most important values.
One thing you could do for a start is read examples in the "Case Studies" section. That would give you a sense of how people track costs and what decisions made a financial difference. Look for case studies where people started in high cost areas, especially. See if their initial costs are similar to yours, or whether even getting to other Mustachians' starting point is a move that would take effort on your part. Then make the needed effort!
