As an American I don't trust most things with a .us TLD. I wouldn't trust another country's TLD, either. But like I said originally -- this is just me. I'm sure others feel like I do but I am not trying to speak for them.
You can, of course, treat domains however you like, but it would be unfortunate to extend your approach worldwide. In many, many other countries the local domain is a strong signal of trust, often more so than a .com/.org.
Thinking through websites I use in Denmark, I struggle to recall one that isn't .dk.
Supermarkets (netto.dk, foetex.dk), public transport (dsb.dk, m.dk, cph.dk), newspapers/TV (politiken.dk, berlingske.dk, dr.dk), University (ku.dk, au.dk), local government (kk.dk), other retailers (computersalg.dk, proshop.dk, elgiganten.dk) ...
The largest grocery delivery company uses nemlig.com, and Ikea uses ikea.com.
As another example, if I'm applying online for a visa to Thailand, that site had better end .th.
A tourist attraction in Guernsey can very reasonably use .gg and maintain full credibility.
