I use ordinary motor oil at 1/10th of the price of "bike" lube and just wipe and lube whenever necessary, and don't think about how often to lube or the oil running out.
Are there any options that are likely to last 2000km between applications?
Yes, a fully enclosed oil bath chaincase.
So do people doing long tours, or things like the TCR apply chain lube daily ?

Only if there's been heavy rain. I use Finish Line wet. Just put it on link by link a tiny drop at a time then wipe off the residue.
I got fed up changing chains and decided to run the whole into the ground on my ROberts (2003, 9 spd Campag). I don't keep a tally of the miles but it's done stuff like
Many North York Moors rides, incl. York to Middlesbrough and back one wintry day and the Moors 'illy Imperial twice,
Phil and Friends several times
Raid Pyrenean (for which I did >3000km just practising). It rained every day. Torrentially.
Cycling in Provence and up Ventoux last last year
plus innumerable rides in the Limousin which is all hills and gear changing
Everything is still in good running order. I don't bother to measure the chain
In fact all the bike has needed in 14 years is new tyres, bar tape and brake blocks. The Brooks saddle has a few splits but they may not be a real problem and the wheel rims may be near the end. Maybe time for a complete overhaul this year.
My tourer is Shimano and I have had many chains, including one that broke when fairly new, and chain rings and cassettes and replaced the rims. It got used for commuting which the ROberts didn't but I have also used it on the touring Raid Pyrenean, a ride across France and a tour in the Alps among other things.
I used dry lube once and thought it was no good, maybe I didn't put it on right?
