I remember a John Stossel special dealing with legislators making bad laws with the best intentions. One example cited was the issue of mandating that infants should have their own seat and seatbelt on air flights. Sounds like a good idea, right? Not really. As he pointed out, such a requirement would force many young families to opt out of flying due to having to pay for an extra seat and they might drive long distances for vacatins or family get-togethers instead -- which would subject the small children to a much more dangerous mode of travel than flying. The result would be more children injured and killed than without such a law being approved -- so far, I believe there has been no such law enacted.
Now here's another issue -- insemination. Recently in the UK the government approved allowing single women and lesbians to be inseminated.

There is a problem though -- there is already a shortage of donors in the UK since there is no longer anonimity of the donors. The UK Parliament made a law that they felt would be fair for children of donors -- the idea they have a right to know who their biological parent is but by doing so many donors opted out of the system. Now you have legislators expanding the demand while the supply is already critically low.

The same is happening in Sweden. The Riksdag recently made a law that lesbian couples could get inseminated. Now they are considering allowing single women such a right -- I will note that in Sweden there are no private egg/sperm clinics allowed and the state basically controls the system. There you cannot be paid for donating (so much for getting very many egg donors) and there too there is no gaurantee of anonimity anymore. So you have a two year waiting list for insemination (not sure about egg implantation) already and (in the name of equality) the government is probably going to create a greater shortage.
The results already are that couples are having to go to countries in Europe that don't have such laws -- it's called "fertility tourism". One interesting story recently was about British couples going to Spain (which has laws similar to the USA in regards to...well, letting individuals decide) but the British couples generaly don't want Spanish donors. So clinics take out adds for male and female donors in Russian and Polish immigrant neighborhoods where you can get donors who are blond and have more northern European facial characteristics.
So it is interesting that just because lawmakers have really good intentions they may create laws that actually hurt the people they are trying to help. This is something people really need to keep in mind whenever someone says "There 'outa be a law".
