You mentioned BISQ but there is hardly any volume for non-European and non-US countries.
Volume is currently the biggest issue by far with all decentralized exchanges. Unfortunately too many people are willing to give up their privacy and security for the convenience of a KYC-enforcing, custodial, centralized exchange. As time goes on, it will change though. It's much like bitcoin itself.
As governments spy more and more on their citizens, as banks decide more and more what their customers are and are not allowed to do with their own money, as corporations mine more and more of your data, bitcoin becomes more attractive to more people.
As more and more CEXs are hacked, freeze more and more accounts, demand more and more invasive KYC, then decentralized exchanges become more attractive to more users.
It's just a real shame that for most people it takes a centralized exchange to screw them over one way or another before they realize the benefits of a platform such as BISQ.
In terms of being forced to use a CEX, check out the great list that malevolent has linked to above. There are a variety of other DEXs you could try if BISQ isn't an option in your area. There are online communities which trade peer-to-peer, including the marketplaces on this forum and various sub-reddits. There are physical stores and ATMs, voucher and gift card exchanges, marketplaces, and so forth. There might well be an option you simply haven't looked in to yet.
