I have tried altering the start with value of an Oracle sequence but I face
[ORA-02283: cannot alter starting sequence number] error.

I tried to find why Oracle does not allow the same but I could not find an appropriate answer for that.
So my question is why is it that Oracle does not let you change a sequence start with value?

(PS: I am hoping there should be a really solid technical reason behind this)

Thanks in advance!

Please give an example ( create sequence + alter sequence ) showing how you're hitting this error.

The following works for me:
create sequence s;

select s.nextval from dual;


alter sequence s
  restart start with 10;
select s.nextval from dual;


Please also confirm which version you're using - this feature was added in 18c.
