I think from an early retirement standpoint, it helps. But I'm not sure we want government programs to encourage people to retire early by giving them subsidies.
For example, I currently live on about $12K/year (but I don't pay premiums on my employer sponsored healthcare). That means I could retire when I get to 300K net worth. Add in premiums pre-Obamacare with a $10K deductible, and I would need another $50K or so (I assumed an average premium of $150/month to account for old age - current premiums would be about $40 on the open market). Add in another $2K per year to pay deductibles, and I need $400K total.
Under Obamacare, my current premium would be $150/month for a ~$6K deductible. That's higher than what I have now. But the key is, when I get to $300K, I can quit my job and live on income of $12K per year. This qualifies me for almost $0 premiums after subsidies. Add in the same $2K/year for deductibles, and I only need $350K to retire. So there's a huge incentive to not work so I can save that $150 premium.
