Security concerns. I’m case of an accident you can sit and maybe survive.
Edit: keep in mind that the Madrid-Barcelona high speed railway line reaches almost 250kph. That’s more than the double maximum speed of a car in Spain.

I’d say that having to buy a ticket with an assigned seat in high-speed trains in Spain has been always been that way.
However, short-route trains (Cercanías) don’t have assigned seat, but they are not high-speed trains.
It will be to keep the quality of the service high, reduce boarding times, or something like that.
