Your repeated references to “modern democratic theory” require a cite at this point, IMO. You have referenced only what appears to be a history of constitutional development. Whose “theory” is this, that you refer to? Yours?
It makes sense that the DC thread makes reference to “No Taxation without Representation”, because that is the accepted title of legislation proposed by Eleanor Holmes Norton (Dem-DC) in 2001, which puts forth the point that DC residents pay some of the highest per capita income tax in the country. Ms. Norton, an elected official, apparently has the ability to introduce legislation, but it is unclear to me whether or not she has a binding vote.
Washington DC also has a shadow representation in Congress.
“Modern Democratic Theory” aside, the issue seems to be more along the lines of how the status of the Federal District (as George Washington preferred to call it) should be seen. The whole point of its existence is that the government should not be beholden to any one state in particular for its home. However, such a status would seem to negate the rights of representation reserved for states, to the potential detriment of its reseidents (who were all but non-existent at the time of the creation of DC). The issue seems to me to be one of administration and status, that is, whether or not DC should become a state in all but name, rather than whether one of the founding concepts of the nation has become “hoary”.
Although the DC delegation is deficient in legislative powers, they are still beholden to the people of DC for whatever benefits their office bestows upon them, and act, at the very least, as a monitor of government actions with a mandate to report back to the voters. The colonial delgates to the 18th century British Parliament were not elected by the colonies, had no such mandate, and were free to impose taxes without even inquiring as to the opinions of the citizens.
Your references to specific situations where the non-represented are taxed can all be remedied through legitimate channels, if the people wish.
The federal government imposes income tax, and if people old enough to work and be taxed but too young to vote are unhappy, they can petition their state government to lower the voting age to 14 or whatever, or pass a law preventing those younger than voting age from working.
As for working resident aliens, their requirement to pay taxes is no different than any other country. If they want representation, they can go home or become a citizen.
Former criminals can move to a state that imposes no such limitation, or they could have considered the consequences of their actions before they broke the law (what a concept).
As for your stadiums and such financed by local taxes, remember that you don’t have to fill out any paperwork or pay those taxes directly. That is a tax the state or municipality places the burden of paying on BUSINESSES, which are free to pass the burden on to the consumer, wherever they may be from. Assuming the business owners are local, they certainly have representation.
Apart from citing any serious academic study, your pronouncements that “No taxation without representation” is some quaint, antiquated notion is just hot air. Back it up, throne-groveller.
