Without everyone's support, even if it could be forced through, there would be no effect. After all, every policy needs people to implement it.
This is the case for the emerging nobility, let alone the old nobles wanting to reform, which is even more impossible.
If I can't complete internal reform, then you shouldn't attempt to be unconventional, everyone must be brought to the same level.
Whoever dares to break the rules is considered a heretic. It's right to gang up and beat them.
The most typical example is Franz the Nineteenth, unanimously considered the most incompetent emperor in human history.
This poor child had a huge list of crimes attributed to him, but in fact, he only did one major thing - the establishment of official schools.
Put simply, he encouraged the nobles to use their heritage to establish official schools at the county, provincial, and capital level to recruit noble children for studies.
