I respect your position. I know a lot of Christian people who feel this way, and I would too EXCEPT that there are still people to minister to in the building who know nothing else, and also because those who know the Lord in my building are also faithful in the streets with the people.

The Lord was a perfectly observant Jew and so did go to the synagogues and temple of His day during His lifetime, preached once (Matthew 4) and turned over the tables a little after His triumphal entry (after Palm Sunday), but He did pass the majority of His time with the people. At least six days out of every seven... and after synagogue or temple, He returned to the people.

The early Christians used buildings too when a particular congregation got too big for a house -- we see that in the book of Acts occasionally -- so I don't think the Bible is forbidding us to assemble in a building on Sunday. I think the problem is that many of us have idolized those buildings and the rituals we do in them, and then neglect the worship and service we should be doing the other six days. So, in a sense, the Lord is using Covid-19 to break the idol, and forcing us to live out our faith in Him every day of the week. Terrible duress, yes, but ...
