For what it's worth, here's my anacdotal experience.

I traded in a Hybrid Camry for a Hyundai Ionic Electric almost exactly 3 years ago.

The Electric version was $40k (it was a demo so about $5k cheaper than brand new) and about $8-10k more than the petrol only model.

The first year of driving it I saved a minimum of $4k in petrol compared to the old hybrid and that is with the electricity costs factored in. Though it was closer to 4.5 when solar was taken into consideration.

This year I saved a bit more due to higher petrol prices and was a minimum of $5k saved compared to the hybrid, and again closer to 5.5 with solar.

Both years I did about 25,000kms. So after 2 years the difference in price has paid for itself, though we still have a loan for the car in theory the extra savings from not paying for petrol will help to pay the rest of the loan off. Though it's mostly being eaten up by inflation.

We are lucky enough to be in a position of semi- owning our own home so we could install power in the carport and solar. If we were renting we certainly wouldn't have done that which makes a huge difference. Also if we couldn't charge at home it'd be a massive hassle to charge away from home, which I've only had to do 5-6 times in the last 2 years. We only have a travel charger at home it is 2.2kw and very slow but we don't, and haven't needed a faster charger.

For battery life, my car has I think, an 8 year warranty on the battery having at least 90% capacity remaining. My range is typically 330kms on a full charge. If I get down to 90% capacity and still have 300kms off a charge I won't notice the difference.

I worked out the rough difference of my car compared to the petrol in terms of carbon emissions from making the battery just using global averages for making batteries. My car hit even with the petrol at about 70,000kms, after that it significantly drops off on the carbon emission side even when using 100% grid power from only coal power while petrol cars keep producing.

For the global average driver at 10,000kms a year it's obviously about 7 years to break even, for myself it'll be the end of year 3 in theory.

I can't say much on replacing batteries even though currently it is very expensive, battery technology and capacity keeps getting better, so one would hope that would mean in the future it would cost less to replace and give you more range. But then how will the shareholders reap the benefits of record profits every year.

I never really did the serving on my hybrid, but I've found the service costs pretty comparable. The last 12 month service was $360 and that includes 22months of roadside assistance.

I want to also mention it is the smoothest car I've ever driven which is nice on long trips.

I know there'll be people who will not care about any of this and others will still consider electric cars bad because of {insert small inconvenience or difference to petrol cars}, but don't let perfect be the enemy of good. They're a good start for individuals to make the change if they have the means, but the largest corporations are the biggest polluters which need regulations and rules put in place before they will start doing there share.

Apologies for rambling.

Lifespan is not really a huge issue. You might lose 5-10% of the battery after 100k miles. Tesla's degradation after 200k miles is 12%. There is much less maintenance that needs to be done on them overall. It is indeed a larger cost up front but even with our cheap gas here in the US, it can pay for itself after 6 or 7 years.

But you are correct that access to them for poorer people. We do need to make a push to at least get level 1 chargers in apartment garages.

As far as environmental impact, cobalt is the worst of it but that is being passed out. Lithium mining is done where there is no life at all. A large chunk of the lithium in our batteries is from the Atacama Desert which has large portions that have no recorded instances of rain. Regardless, it is still significantly better than using fossil fuels in internal combustion engine.
