Of course not.  But huge financial opportunity does cause innovation.  And healthcare is going to continue to be a huge financial opportunity.
I think you are assigning me a position and an argument that I haven't made here.  I don't recall complaining about wasteful defense spending.  
That aside, I have no idea why you say that the government would have much weaker incentives to get healthcare right than defense.  Most voters don't know or care how defense money is spent.  Most voters will notice if their healthcare is messed up.  It seems to me there would be considerably more pressure to get it right with healthcare.
		
		
	 
A couple points:
1. Total amount spent doesn't mean financial opportunity. Altria, for example, is a huge company, and a very profitable one, but the antithesis of a growing, innovative one. Likewise public utilities, which are probably a fairly comparable equivalents to the sort of "private sector" that will be left after this mess, are rarely described as "innovative" despite basically having license to print money.
2. Regarding defense, no, I wasn't saying you make that argument per se, I'm just furthering the parallel you raised.
3. Government has much weaker incentives to provide good health care than defense because the latter is a (mostly) 
public good and the former is a (mostly) private good. In plain English, when we collectively purchase "defense", we all become more secure. Some of us may value the security differently, but my use does not diminish yours.  In health care, expending resources on my care does no obvious benefit to you, but comes at an obvious cost.  We'd all like lots of health care spending for ourselves, our friends and our family, but we're quite a bit less willing to spend on the health of others. Especially if it comes at the cost of spending on ourselves.
	
	
		
		
			So do you agree that healthcare reform will cut costs?  If so, great, I am happy to concede that a smaller amount of spending on healthcare will lead to lower financial opportunity for innovators.  On the other hand, if you don't actually believe that it will cut costs, then you can't really honestly complain about cost cutting, can you?
		
		
	 
I don't know, but I can certainly honestly complain about reducing financial incentives to innovation regardless, because, as I noted above, purely "spending a lot" is not a financial incentive to innovation. If I agree to purchase every $10 pepperoni pizza you produce, but specify it must be a 14" pizza with X amount of crust, Y amount of cheese, Z amount of sauce and no less than 1 pepperoni per square inch of pizza, and I refuse to buy any other sort, it doesn't spur a pizza maker to go out and make a tasty 
Kentucky Country Ham and Fig pizza. Especially if I'm in charge of collecting everyone's funds for then paying for everyone's pizzas, because then there are that many fewer people who have the available funds and choice to go out and try the new kind.
	
	
		
		
			Like I said, I agree with that generally, but it is not an on-off switch.  It's not all or nothing.  It's not black or white.  And innovation is not the one true good which must be maximized at the cost of all other variables.
		
		
	 
As a long run proposition, I'm fairly confident it is. From any sort of principle of maximizing human well-being at least, we get more benefit from improving our lot than trying to redistribute the benefits in a manner that freezes ourselves in time. Pick any moment in history, and the average person is certainly better off today than the moment you pick. For most of history it's not even a remotely close comparison. Even going back 20 or 30 years, people routinely live now from things people routinely died from. Today's poor are generally demonstrably wealthier than yesterday's poor. Slowing this process is always a danger because 2-3% increases in productivity aren't easily noticeable in an immediate basis, so it tends to be discounted and taken for granted. In reality, however, they make big and fairly noticeable improvements to folks' lives over slightly longer periods of times. 
And of course, we're talking about improvements to billions of peoples' lives. In contrast, the proponents of government takeover have, frankly, not demonstrated much in the way of tangible benefits to their proposal which comes at tremendous costs in both the short run and long run. At best, most of the problems they seem to (potentially) remedy are problems due to existing efforts of government to improve and control the situation. But as is usual with government, the only solution is more cowbell.
