Talking about code it is possible to build a community website not using outpost but it will always take time to do a proper frontend ensuring that everything it is correctly working.

In my opinion maybe we will not have that concluded fastest enough.
When I said to start with outpost it was to be able to start the ads in the front end from day 1.

About create a costumo community without a token and afterwards launch a token I think that is possible at least I never heard anything saying the opossite.
