Which, again, is an argument about it being very easy to do.

That does not address jamesrcole's argument. He's not saying "it was always possible, therefore being easier is no different".

He's pointing out that there are worse bad things that are just as easy to do, yet they aren't considered scary.

You can't make an argument that the ease matters, because he's asking about things that are equally easy if not easier. Why is easy availability of such a drug different from easy availability of the knife/car/etc.?

It's a value judgement of course. As a society we accept that n deaths/year are worth it for the benefits that cars and butter knives bring to the wider population. In very recent history, sterilisation techniques have been massively abused by governments in an organised way. There was never a large-scale, systematic programme of running people over as policy. Forced sterilisation is still a thing in India...

Means that can be used to kill people have also been abused.

You should be focused on access, control and any inappropriate uses. Not on whether the things being used exist or not.
