Do you qualify? Then you are exempt from such a ridiculous amount that it is hard to argue this.
Or maybe you visit the USA too much to qualify? In which case you do have enough ties that I think tax makes sense.
If you buy a house, things are going to be complicated.
If you have a workplace pension from your job, you're probably screwed. State pensions have screwed people too.
If you invest in stocks, or mutual funds, you'll pay more in tax preparation than you'll make.
If you set up your own company and are not paid as an employee but as the owner, you will be screwed.
Rent out a property, screwed.
Fail to declare every account that you're a signatory on? Prepare to pay up to 125% of the contents.
If you're children are beneficiaries of a trust set up by their non-american grand-parents? Totally screwed.
You might also think it is "ridiculous" because you only earn money from a paycheck (e.g. you are an employee). For the self-employed things look very different: your revenue might easily be $200k, while your actual income is half that. Your foreign business pays taxes on income, but claiming the same deductions in the US might be difficult or impossible, so you might end up paying taxes on your $200k of revenue.
More importantly, though, the amount of paperwork that the US requires (FATCA and FBAR reporting) is ridiculous. And preparing your US taxes if you are an expat is a minefield, there is no way you can do it yourself. You need help from experienced tax accountants. All in all, it is a significant burden.

If your income is above $100k, you also have to fill out the AMT worksheet, which may result in you needing to calculate everything to deduct the foreign taxes you've paid.
If you have US stocks and sell them, you have to worry about paying capital gains taxes to the US (they consider this US income, regardless of if you received the stocks as part of your employment), and you generally have to pay taxes to the country you're living in for that as well. If you're lucky you might be able to deduct the US taxes or expected taxes, otherwise you might not be able to do so or might not be able to do so until the next year.
You also have to report your overseas accounts every year.
When I first moved overseas, yes, it was pretty simple to just fill out my 1040 and my form 2555. Last year I needed those plus the 1040 Schedule B and form 1116. Next year things will get even more complicated since this year I bought an apartment, so there's a mixture of rent deduction and mortgage deductions, plus a significant capital gains tax burden due to selling stocks for my down-payment on the apartment.
Though, I am curious, since my wife is a US citizen, and we are living in my home country; does the 200k if married limit count, if your spouse is a foreign citizen (like say, me)?
That the U.S. government makes demands of people living outside its borders is preposterous.
