Well, if you don't mind the dividend taxation nightmare, huge bid/ask spreads when trading relatively rare ETFs like Vanguard in Europe, currency exchange issues, potentially having to deal with the US IRS to get some of your taxes back, idiocies like stamp taxes (when trading in places like London) and all the other inconveniences not yet mentioned then go ahead, buy Vanguard.
I don't know what the situation is like in your country, but be prepared for another potential surprise when you finally decide to sell your dividend-paying ETF. You will most likely have to pay taxes on your capital gains (depending on your location, that's expected), but even funds like those from Vanguard sometimes have accumulated dividend-like gains. This sounds totally idiotic, but I just checked my government's web site, it is true. So your government most likely subtracts what it thinks its theirs in taxes and then YOU, the investor (or your heirs), have to prove to your tax man that you already paid on all these accumulated dividend-like gains for the last 25-50 years to get that money back. I hope your paperwork is in order, complete and spotless if your tax agency decides to disagree with your claim. Otherwise you pay twice.
Institutional investors don't care, they have accountants and tax experts at their disposal, they deal with bigger headache-inducing problems all the time. But the average private investor? Good luck.
That's why investors in my country call some ETFs "tax-simple", while others are rated as being "tax-ugly". Vanguard's ETFs definitely belongs in the latter category, the mentioned LUxxxx ETF is in the former category. LUxxxx was just an example anyway which I mentioned in that other thread. If all that is totally different and no issue in your country, cool. I hope it stays like that, but I wouldn't bet on it.
The ETFs discussed in the link above (say, LU0392494562) in my opinion are inferior, as they tax the dividends more, even though the dividends are reinvested. The prospect of the LU0392494562 fund reads
The net dividends reinvested in the index correspond to the respective gross dividends less a notional withholding tax. At present the rate used for this is the maximum withholding tax rate levied on foreign domiciled institutional investors who do not benefit from a double taxation convention.
The reason for this is the index this ETF tracks, which happens to be the MSCI
Total Return Net World
Index (TRN). That's how the index is calculated, as if the dividends were taxed at a certain rate and then immediately reinvested. Of course there aren't any dividends being reinvested and taxes paid, because there are no taxes on derivative trades. You might be able to find another ETF which tracks another MSCI World index that doesn't pretend to pay taxes, dunno if those exist... probably, somewhere.
I recently saw a post on another forum where someone calculated the difference between those "swappers and dividenders" using real world examples and the synthetic ETF came out ahead. If you have to wait for the money to reinvest and pay trading costs etc. you lose.
If you happen to find a European broker which 1. lets you trade at Wall Street for a few bucks and is 2. kind enough to provide you with all the necessary paperwork so you will get your taxes back in a timely manner (3. for free or a low fee) and 4. happily accepts foreigners then I'm all ears, hope you will let us know about them.
If you are happy to pay taxes on your dividends every single year then there are replicating European ETFs which you can trade literally everywhere, without huge bid/ask spreads, without currency issues, without potential taxation surprises etc.
