Is it stupid to buy a house if I don't know when and where I want to settle down?

Hello,

I live in Hungary, and the government is planning to give people mortgages with a very low 3% interest rate (the inflation rate here is over 9%), which is an insanely good offer. I'm in a financial situation where I could comfortably buy a flat in the capital city, and I feel like I shouldn't miss out on this opportunity cause this might be my last chance to buy a flat.

My issue is that I don't want to settle down just yet, I like that with renting I can pick and choose where I live. I'm planning to take a 1-2 year mini retirement in 2 years, where I travel the world in a car, do seasonal jobs and random jobs I find, or I find a remote job and travel full time. I might not even return to Hungary. I don't like responsibilities, and having to pay a morgage every month also gives me anxiety.

At the same time this low mortgage rate is a really good opportunity, and having a house would give me some security in case I decide to settle down.

Has anyone been in a situation like this? How much does owning a house with a mortgage complicate your life?
