Note - I immigrated to Ireland from the US and went through the visa process (including huddling in the cold in January at 4 AM at burgh quay, and years later, writing a scraper for their insanely bad appointment system that managed to actually be worse than huddling in the cold)

It's pretty normal not to be able to look for work on a tourist visa in most countries - are you suggesting this is unusual? As far as spouses, they used to have an incredibly asinine system where they told you your spouse _could_ work, without sponsorship, if they got a special form, but getting this form was de facto impossible. It was a very Irish approach, in retrospect. The campaign to fix this was, eventually, successful. (https://reformstamp3.wixsite.com/home)
