Virtually any airline outside of the no-frills-Ryanair sector happily sells you flexible tickets (often for price).

You must not have had the DB ICE4 experience. I'd rather jump off an office building than to sit in one of their second-class cars ever again. They are extremely space-constrained, and now they build the window walls slightly round (and rounder so than e.g. mid-range aircraft cabins), so you sit in there with an arm folded to the inside, like Ötzi. On my ride back, I shredded the already-paid ticket and bought a new one for First Class, which was only slightly better. No European airline even comes close to that awfulness (and yes, I've had non-Business Ryanair experiences).
Planes may be more uncomfortable, but at least they don't make you sit down for half a day.
> But for many people, having fewer steps in the journey
Are you aware how often you have to switch trains if you are doing point-to-point travel? Even within Germany, I have 4 switchovers between where I live and Berlin (that is, if I am lucky). With the plane? Sit down, stand up, Berlin.
> being able to comfortably work
Unless you travel First Class AND get a seat with a table AND somehow are able to work without internet, I don't see how that argument (which comes up every once in a while) works out for you. YMMV, depending on which country you are in.

This is not the same thing. I do not need to tell anyone that I have decided to take a later train using my open train ticket.
Yeah and the amount of space is not really anything specific to the train. You can vary the amount of space in planes, buses and cars as well, and the price will follow, just as in trains.
There is no reason why space is "cheaper" in a train really, it's only the scheduling of few trips that make more space available, if you have more trips on the tracks, similar to a road, space becomes constrained, like you see in subway trains.
Furthermore, to make a fair comparison you need to:
- Include all the costs of the air ticket in the price comparison, in particular transport to and from the airports. Public transport is sometimes not available, or may not be convenient (e.g. with luggage or small children), and due to the large distance to many airports taxis can be very expensive
- Include all of the time involved in the flight — depending on the cities involved, your two and half hour flight could easily be 5+ hours city-centre-to-city-centre once local transport, check-in deadline, time padding for uncertainties etc is considered.
- Compare to a rail ticket for a specific train at a specific time, which is usually cheaper. The more expensive rail tickets often give you the option of multiple trains on a given day, which is a level of flexibility no air ticket gives you.
If we want to really make it a fair comparison you should also probably compare the price to the business class flight ticket, considering that even the lowest class of train ticket gives you a comparable level of comfort to a typical intra-Europe business class airplane seat.
If you need to get there as quickly as possible, the airplane is going to win on most (but not all) routes. But for many people, having fewer steps in the journey and being able to comfortably work during the journey can actually make the longer train option more convenient.
