Why isn't ethanol written as ethan-1-ol or something similer?

there is only the one possible form. If it looks different, it is because you are looking at it from the wrong side. Flip it over and you will see. It is a symmetry question. You need an asymmetry to have a distinct and unique form. The alcohol group can only be on an end carbon. there is no front or back carbon, so the ends are the same thing.

ethanol is CH3-CH2OH
The OH can only go in one place.
With propanol it can go either on the first or the second carbon so propan-1-ol and propan-2-ol are possibilities.

Ethanol can only exist in one form as the carbon chain is so short.

Because, with only 2 carbons there is no need to designate which the single hydroxyl group is attached to as it makes no difference - and the IUPAC nomenclature conventions prohibit unnecessary labelling
