Germany (€), Japan (Yen), Switzerland (CHF) etc. invest huge sums into R&D, there's innovation around every corner be it in top-class universities or world-leading companies.
These are fully industrialized countries not for 2-3 years but for decades ! Just imagine how much money is in their innovation cycle each years ongoing for decades.
What these countries produce will always be in demand on world-market until someone shows up who can gain market-shares from them at their expense.
Just
like Turkey is now doing in high-tech weapon sales.
Let's see where automobile industry is going with e-vehicles and new heavyweights like Tesla, Chinese brands etc. and see whether Volkswagen will be able to pay same wages in their German or EU-outsourced factories in 10 years time !
When Tesla first showed-up German media was laughing at Tesla, now they're shitting their pants from the arised competition.
For now German economic model is sustainable.
But their is no godly law declaring that German, Swiss economy will be successful forever as other nations
including Turkey push into high-tech sector.

Turkey is not at the development level of Germany or Switzerland.
EU-Turkey customs union started 1995 and EU is Turkey's biggest trading partner.
Turkey ran trade-deficits with EU
continously.
How sustainable is that model I ask you ?
In 2019 with weakening TL Turkey has achieved a small trade surplus with EU.
Unlike EU the population in Turkey is growing 1 million each year, Turkey has to create jobs.
How you'll be creating jobs when you import more than you export ?
You want strong TL at this stage of Turkey's development you agree with Turkey running chronic deficits, Turkey becoming more dependant on outside than getting more self-sufficient.
EU statistics provide an analysis of the international trade in goods between the EU and Turkey, by member state and by type of goods exchanged.

And when you say "Lira is only 1/10th worth of 20 years ago" then you have to remember that Turkey is a much different country than 20 years ago.
Turkey exported 28 billion $ worth of goods in 2000.
Textiles being the biggest export items, and Anatolia being mainly an agricultural country with electricity outages and more 3rd-world vibes the more east you go into Anatolia. Same with literacy rates !
So, my question to you is simple:
How are you going to lift Turkey to the next level with strong TL given Turkey is fully integrated into world-markets and Turkey has developed so many new trade relationships ?
You can't sell machinery to Africa where Africans say to themselves "Hell, I can pay the extra 15% and get the proven German or Italian machine ! " and on the way bankrupt yourself because you're running chronic deficits with strong TL in any statistical category.
