Research is growing. (True, but that is independent of OA.)
Publication costs are not a large percentage of total research costs. (True, but publication costs are already being paid in full, today, by subscription fees; any new publication charges today hence mean additional funds redirected from research -- or from elsewhere -- to double-pay, unless the existing subscription fees are redirected toward paying the publication charges.)
OA enhances research progress. (True)
Author publication charges are not new (in some fields). (True, but new OA publication charges, today, would be new, and additional, unless their payment was redirected from subscription savings.)
Mandated Green OA could cause subscription collapse. (Possibly, but if it did, that would simultaneously release the subscription savings to be redirected to pay for Gold OA publication charges [probably reduced to just the cost of peer review]; and meanwhile we would already have 100% [Green] OA, either way.)
In some fields, Central Repositories (CRs) like Arxiv have a larger Green OA percentage of total research output than Institutional Repositories (IRs). (A few fields do provide Green OA, unmandated, today, but most don't; that's why we need mandates; IRs that mandate Green reach 100% OA within about two years; institutions and funders mandate; "fields" do not; institutions wish to record, showcase, and maximize the impact of their own research output; "fields" do not; CRs can harvest from IRs; the locus of deposit for mandates should be researchers' own IRs.) ...

The open access movement:
Putting peer-reviewed scientific and scholarly literature
on the internet. Making it available free of charge and
free of most copyright and licensing restrictions.
Removing the barriers to serious research.
I recommend the OA tracking project (OATP) as the best way to stay on top of new OA developments. You can read the OATP feed on a blog-like web page or subscribe to it by RSS, email, or Twitter. You can also help build the feed by tagging new developments you encounter.
