It is similar in the USA. You can't transfer a TB20 to Experimental category.
This is the price paid for ICAO and its huge privileges: unrestricted worldwide flight, IFR and night.
To some people this is priceless. To many people this is worthless, but they have loads of options on the "light/sports" scene.
IMHO there is no point in moaning about this because it will never change.
ICAO is what has protected GA from left wing / dictatorial politicans going after "rich bastards" in most countries in Europe (those that do not have a long GA history, like UK and Germany) would have simply banned GA, decades ago.
The trick is managing a
CofA plane cost effectively. I have already laid out how you do it
One other thing: base maintenance on strict
airborne time. This is 100% correct and - for typical GA burger run flying - will save about 20% on maintenance.
Arguing that one's hour meter doesn't work that way but counts hours all the time the oil pressure is up, etc, etc, etc, is like saying one is flying full-rich (and wasting about 30% extra fuel as a result) because one doesn't have EGT / CHT gauges.
