From my perspective this is the problem I had with it. He has a lazy attitude towards everything from the start. Thats fine if there was growth later on.
So when the country is trying to track him down that was the time to show his growth. Show that you need strength to survive.
Only reason he survived is he got lucky, the girl and those adventurers helped him but that didnt trigger any I need to level vibes. He still stayed way too chill about it.
Then the girl who basically committed treason to smuggle him out he chooses to abandon meeting with her. Dude is an idiot. Now you could say he was being cautious etc but no he doesnt really use his brain so he definitely wasnt being cautious..... he didnt think that someone committed treason for him and is a merchant they could be a good connection for him in a world he knows nothing about.
Then the girl helpshim escape again and after this I would think If people for coming for you and you barely escape you would want to gain strength. He even saw that he gains exp and levels when people in his party fight.
He has money he could hire people with his money to ride a bus for exp to quickly level but despite knowing and mentioning he gains experience from party he doesnt. He literally gained levels last time like that when he was being escorted. He randomly found he gains levels that way so why not use that. If he's lazy he can be atleast smart about it.
He comes across cards and things when h's hunting and I recall him saying I can just get by picking up loot there is no need to fight (level) etc something along those lines.
You could say its humor but by that time you have had 2 near death experiences I would think you would take this a little more seriously to be stronger to stand up if the country comes for him.
Also I think he has the most op cheats. Think about his ability he can literally go around picking up summoning cards, and the way his skills are setup he can be unimaginably op compared to the others.
He can use hired party to level, pick up loot summonings etc and create things for money....i mean that is literally a super op setup if you use your brain properly.....
His lazyness and lack of being smart prevents him from maximizing the skills properly....
Also you mentioned that quicker he draws attention to himself but you also have to think that he is racing against the clock. The other side has a lot more resources then him so he needs to level or be stronger in his own way to to fend them off. Also make connections etc but as you saw he tried to abandon the merchant who basically is tied to the biggest merchant group without being aware or trying to learn he would have missed his opportunity. Conveniently it didnt happen but it wasnt due to his own planning or smartness but coincidence he got saved by the merchant girl and then they went together once again.
I mean I also know that cant expect the story to be perfect asmajority of isekais are recycled trash. The suggestions I was saying could make it better but this is definitely readable compared to some super trash ones I have come across
