Yup, the same works for passports from other countries like Malta and Cyprus which iirc literally just sell citizenship.
Google golden passport. Portugal and Spain were at it but I think many countries have shut down the programme.
Not quite so simple, but makes things certainly easier.
"As an EU citizen, you have the right to move to any EU country to live, work, study, look for a job or retire.
You can stay in another EU country for up to 3 months without registering there but you may need to report your presence. The only requirement is to hold a valid national identity card or passport. If you want to stay longer than 3 months, you may need to register your residence.
In many EU countries, you need to carry an identity card or passport with you at all times. In these countries, you could be fined or temporarily detained if you leave your identity documents at home - but you cannot be forced to return to your home country for this reason alone. "

It absolutelly is as simple a travelling there and finding a place to stay.
I’ve moved, lived and worked in 3 foreign EU countries just like that.
Those rules about identity documents and registration apply also to the locals: some countries want people to be registered with the city hall of were they live and (supposedly, though in 2 decades I was never asked for it) carry identity papers (though if you have an identity card from your home country that’s valid all over the EU), others couldn’t care less.
You don’t need any kind of visa or even have a job: as long as you can support yourself (i.e. aren’t there to leech of social security) it’s all fine.
That residency status is all conditional in many ways:
As an EU citizen, you have the right to move to any EU country for a period of up to 3 months as long as you have a valid identity card or passport. If you want to settle in another EU country but you have no intention to take up any work or education there, you need to prove that you:
have sufficient resources for you and your family during the time you want to stay in your new country
have comprehensive health insurance
Reporting your presence and registering your residence
During the first 3 months of your stay in your new country, as an EU citizen, you cannot be required to apply for a residence document confirming your right to live there - although in some countries you may have to report your presence upon arrival.
After 3 months in your new country, you may be required to register your residence with the relevant authority (often the town hall or local police station), and to be issued with a registration certificate.
You will need a valid identity card or passport and:
proof of comprehensive health insurance
proof you can support yourself without needing social assistance benefits: resources may come from any source, including from a third person.
Can you be requested to leave or be deported?
You may live in the other EU country as long as you continue to meet the conditions for residence. If you no longer do so, the national authorities may require you to leave.
In exceptional cases, your host country can deport you on grounds of public policy or public security - but only if it can prove you represent a genuine, present and sufficiently serious threat affecting one of the fundamental interests of society.
The deportation decision or the request to leave must be given to you in writing. It must state all the reasons for your deportation and specify how you can appeal and by when. Permanent residence
If you have lived legally, meeting the conditions to stay in another EU country for a continuous period of 5 years, you automatically acquire the right of permanent residence there. This means that you can stay in the country as long as you want, you are entitled to be treated as a national of that country and you enjoy more protection against deportation. You can apply for a document certifying permanent residence.
Your continuity of residence is not affected by:
temporary absences (less than 6 months per year)
longer absences for compulsory military service
one absence of 12 consecutive months, for important reasons such as pregnancy and childbirth, serious illness, work, vocational training or a posting to another country.
You can lose your right to permanent residence if you live outside the country for more than 2 consecutive years.

Going with a non chalant attitude of ‘lel I think I’m just gonna go live on the other side of EU now’ will land you in some trouble in most cases, what ever your personal alleged experience is.
Better be prepared with the proper info than leave it to luck and feels.
