I am simply approaching this from a logical perspective using comparisons (as I generally do). Whether or not screening should take place, I do not know, but I do know this much:
- Just about any country in the Western part of the world has seen restrictions on smoking in public and at work places (fair or not, I am not to judge). Now comes the point of logical inference: if legislative measures are brought forward to protect, say, office workers from 2nd hand smoke, then why not (also) protect unborn babies? Are office workers somehow more important?
- Screening is already used in many places: breathalyzer tests for motorists, drug tests in schools, drug tests at work places, drug testing for army recruits, etc. Now, people may think that such tests interferes with their personal freedom. That is of course a matter of personal opinion, but again, I do know this much: if we can - as a society - accept/tolerate screening for such a wide area of the population (e.g. schools, work, driving) then why not for a sub-set of society such as pregnant mothers? Again... just a logical inference here.
You already do. See 2nd bullet point, above.
Carbon monoxide screening has nothing to do with eugenism. Bringing forward "favourable genes" (i.e. desirable traits such as colour of hair) - that's eugenics (as opposed to ensuring the best possible health of existing genes - regardless of, say, colour of hair).
In addition, you might want to see this:

Lastly, just to keep this thread a little "on-topic" in relation to tinnitus/hearing, I would like to mention that modern studies keep highlighting new ways that smoking affects unborn babies. Previously it was generally accepted that only seriously underweight babies (< 1750 grams) would have a chance of impaired hearing. However, it is now known that smoking during pregnancy leads to a 3-fold risk of mild hearing loss (regardless of weight of babies):

Now... the above is just one area of health that smoking during pregnancy affects. There are many more. If you think it is reasonable that children should be born with defects to their hearing, and perhaps increased risk of developing tinnitus later on, that is of course your choice. But I think otherwise.
Lastly, here is a comparison photo of what happens to the movements of a fetus when a mother smokes:

Sorry to keep it off-topic but …
Of course I don't think it is reasonable that children should be born with defects to their hearing, nor do I think that there's no problem with pregnant women smoking, I'm just saying that the way you suggest (because you suggest things at least, even if in a subtle way) to fix that would by no mean an effective one (neither a desirable one). We need education and sensibilisation to make people understand the issues at stake and make them stop by themselves those kind of behavior … otherwise, you could have all the screening or any kind of authoritative and intrusive measures, people will always find a way to do such kind of bullshit … and if a government or political regime would take such kind of measures (screening of pregnant women), they would take the risk to open the way for more authoritative and intrusive measures regarding many other aspects of life, because when you start like that you never know where it would stop, and who would be legitimate to put the limits and where ? I'm sorry, but that's the principle of totalitarism, or at least it could lead to it.
And yes of course it has something to do with eugenism, at least in a broad sense or at least historically, guess which political regime initiated the first anti-smoking policies of modern era ? (and it was no coincidence, they did it with very clear eugenist considerations in mind) A regime that had a precise view of what should be the health status of their population and very authoritative way to ensure the best health status of their population (at least they thought that's what they were ensuring with their policies, but of course it's controversial).
Don't get me wrong, i'm not drawing any comparison with what you wrote, but we should just keep in mind that the way a society keep a control over people's behavior, and which kind of control we are ready to accept and/or to find socially legitimate or acceptable, is not only a matter of logic (as you claim you use to draw what are your own conclusions), but rather a political thing (in the true/substantial sense) such that there's not only one-logical-way-to-govern-society (which is a scary concept, leaving no room to political/democratic debates and decision making)
